The top of a ladder weighing 20kg and 6m long rests against a vertical wall and the foot of the ladder on a horizontal floor. For the wall, f=0.15, and for the floor f=0.20. How far up the ladder can a man weighing 60kg go before the ladder begins to slip?

Answers

Answer 1

The ladder distance a man weighing 60kg go before the ladder begins to slip is 2.973m.

What is friction?

   

The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction.

There are various kinds of friction: Two solid surfaces in touch are opposed to one another's relative lateral motion by dry friction.

Here, it is given that:

Weight of man = 20kg

[tex]N_1=f_aMg\\N_2=f_bMg[/tex]

Momentum = 0

So,

[tex]N_1-N_2=-WgX[/tex]

[tex](f_a-f_b)20=-60X[/tex]tanФ

(0.15 - 0.02)20 = -60X x 3/5

x = 1/36

x = 0.027

Now, the distance will be 3 - x = 2.973m.

Thus, the answer is 2.973m.

The boy of mass 42 kg is sliding down the spiral slide at a constant speed such that his position, measured from the top of the chute, has components r = 1. 5 m, θ=(0. 7t)rad, and z=(−0. 5t)m, where t is in seconds.

Determine the components of force Fr, Fθ, and Fz which the slide exerts on him at the instant t = 2 s. Neglect the size of the boy

Answers

The components of force Fr, Fθ, and Fz that the slide exerts on the boy can be determined by using the principle of conservation of energy. According to this principle, the total mechanical energy of the system (boy + slide) is constant.

This means that the sum of kinetic energy and potential energy must remain constant as the boy moves down the slide.

The kinetic energy of the boy can be calculated as:

K = (1/2) * m * v^2

where m is the mass of the boy and v is his speed. Since the boy is moving at a constant speed, we can assume that v is constant, so the kinetic energy remains constant.

The potential energy of the boy can be calculated as:

U = m * g * h

where m is the mass of the boy, g is the acceleration due to gravity, and h is the height of the boy above the ground. As the boy moves down the slide, h decreases and U decreases.

Now, the net force acting on the boy can be calculated as:

F = m * a

where m is the mass of the boy and a is his acceleration. The net force is equal to the sum of Fr, Fθ, and Fz, the components of force exerted by the slide.

At t = 2 s, the position of the boy can be determined using the given equations:

r = 1.5 m

θ = (0.7t) rad = (0.7 * 2) rad = 1.4 rad

z = (−0.5t) m = (−0.5 * 2) m = −1 m

Substituting these values into the equation for potential energy:

U = m * g * h

U = 42 kg * 9.8 m/s^2 * (-1 m)

U = -408.4 J

The net force acting on the boy can be calculated as:

F = ΔU / Δt

F = (U2 - U1) / (t2 - t1)

where U1 and U2 are the initial and final potential energies, and t1 and t2 are the initial and final times. Since the boy is moving at a constant speed, the net force is equal to the sum of Fr, Fθ, and Fz.

Finally, the components of force Fr, Fθ, and Fz can be calculated using the equations for force and using vector components:

Fr = F * cosθ

Fθ = F * sinθ

Fz = F * cos(90° - θ) = F * sinθ

In conclusion, the components of force Fr, Fθ, and Fz that the slide exerts on the boy can be determined by using the principle of conservation of energy and vector components. The net force acting on the boy is equal to the sum of Fr, Fθ, and Fz and can be calculated by considering the change in potential energy as the boy moves down the slide.

Plaster  would be best suited to curved ceiling surfaces. Plaster is a versatile material that can be molded and shaped to fit curved surfaces, making it ideal for covering curved ceiling surfaces.

Plaster is a versatile material that can be molded and shaped to fit curved surfaces, making it ideal for covering curved ceiling surfaces. Unlike drywall, plywood, or wood planking, plaster can be applied in a thin layer to conform to the shape of the curved surface. This allows for a smooth, seamless finish that seamlessly blends with the curves of the ceiling. Additionally, plaster dries to a hard, durable surface that can be painted or textured to match the design of the room. For these reasons, plaster is often considered the best option for covering curved ceiling surfaces.

In addition to its versatility and ability to conform to curves, plaster also has several other advantages when used on ceiling surfaces. Firstly, plaster is a fire-resistant material, which makes it a good choice for use in areas where fire safety is a concern.

Currently, this Linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. The database application and the associated data will take up over 200GB of hard disk space. In addition, these 100 users will store their personal files on the hard disk of the system. Each user must have a maximum of 5GB of storage space. The department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. How much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? Where would these partitions be mounted? What quotas would you implement? What commands would you need to run and what entries to /etc/fstab would you need to create? Justify your answers.

Answers

Given the requirements and constraints, you will need to ensure that the system has sufficient hard disk space to accommodate the database application and the user data, while also ensuring that the system remains stable and free of hard disk errors. To do this, you will need to take the following steps:

Add Hard Disk Space: You will need to add enough hard disk space to accommodate the database application and user data. Given that the database application requires over 200GB of disk space, and each user requires 5GB of disk space, you will need a minimum of 200 + (100 x 5) = 700GB of hard disk space. If you have a spare 1000GB SSD available, you can use that.Create Partitions: You will need to create two partitions on the hard disk: one for the database application and another for the user data. Given that the database application requires over 200GB of disk space, you should create a partition with at least 200GB of disk space for the database application. Given that each user requires 5GB of disk space, you should create a partition with at least 100 x 5 = 500GB of disk space for the user data.Mount Partitions: You should mount the partition containing the database application to the /var/lib/mysql directory, and the partition containing the user data to the /home directory. This will ensure that the database application and user data are stored in separate partitions and do not interfere with each other.Implement Disk Quotas: To limit each user's disk usage to 5GB, you will need to implement disk quotas for the /home partition. You can do this by using the quota command, which allows you to set disk usage limits for individual users or groups of users.Update /etc/fstab: You will need to update the /etc/fstab file to specify the partitions that you have created and the mount points for those partitions. This will ensure that the partitions are mounted automatically when the system is started.

Here is an example of what the entries in /etc/fstab might look like:

/dev/sda1 /var/lib/mysql ext4 defaults 0 0

/dev/sda2 /home ext4 defaults,usrquota 0 0

To implement the disk quotas, you will need to run the following commands:

# touch /aquota.user

# chmod 600 /aquota.user

# mount -o remount /home

# quotacheck -avugm /home

# quotaon -avug

These steps should ensure that your Linux system meets the requirements and constraints set by the department manager, while also providing a stable and efficient system for the 100 users who will be using the database application.

The mass of the Pacific Ocean (a) in slugs is 4.60 × 19⁻¹⁹ slugs and (b) in kilograms is 6.71 × 10²⁰kg, with an of area 64,186,000 square miles and its average depth of 12,925 ft.

What is a slug?

In the US standard system of units, the slug serves as the unit of mass and the pound serves as the unit of force. The British Imperial measuring system and the US customary measurements system both use the slug as a derived unit of mass. Systems of measurement either define mass and derive a force unit or define a base force and derive a mass unit.

Given:

V = (64,186,000 mi²) (12,925 ft) (5.280ft / 1mi)²

= 2.312 × 19¹⁹ ft³

(a) m = ρV = [(64lb/ft³) / (32.2 ft/s²)] (2.312 * 10¹⁹ ft³)

= 4.60 × 19⁻¹⁹ slugs

(b) m= (4.60 * 10¹⁹ slugs) (14.59 kg/ 1 slug)

= 6.71 × 10²⁰kg

what is the direction and magnitude of the electric dipole moment of the electric dipole shown below? give angle from x with counterclockwise defined as positive and clockwise as negative.

Answers

A vector measure called the dipole moment has a direction that goes from a negative to a positive charge. The formula p = qd, where q is the separation between the two charges and q is their magnitude, is used to get the electric dipole moment.

A dipole moment is the measurement of the separation between two electrical charges that are in opposition. A vector quantity is a dipole moment. The charge multiplied by the separation between the charges yields the magnitude, and the direction is from negative charge to positive charge: μ = q · r. The formula below is employed to determine a chemical bond's dipole moment: Where q is the size of the separated charge, r is the separation between the charges, and is the bond dipole moment, the formula is: = qr. Acting in the vector quantity's direction is the dipole moment. A dipole is made up of two charges that are equal and opposite and are spaced apart somewhat. The dipole moment is the result of the charge and their distance from one another.
