In other words, an object possesses mechanical energy when it has the ability to do work due to its position or motion. Mechanical energy can take the form of either kinetic energy, which is energy due to an object's motion, or potential energy, which is stored energy due to an object's position.
Some examples of mechanical energy are:
Hydro power plantCyclingWrecking balls, etcWhat is Mechanical Energy?This refers to the type of energy that an object or mass possesses based on its motion and can either be potential or kinetic energy.

Which option identifies what process should be used as a model for design in the following scenario?
John is developing a handheld camera, unlike any others that have been developed before. Even though he understands what the final product will be, it still requires further development and modification.
A. engineering design process
B. reverse engineering process
C. structural process
D. brainstorming process
Answer:
A. engineering design process
Explanation:
We are told that John is trying to develop a handheld camera. And that it is unlike any other one that has been developed before.
Now, though he understands what the final product will look like, the camera still required further development and modification. This is simply an engineering design process because it involves finding a need and trying to solve it since he already understands what the final product will be.
How can you determine the driver & driven gears in a gear train?
The driver gear is the gear that provides the power to turn the other gears in the gear train, while the driven gear is the gear that is turned by the driver gear.
How to identify the driver?One way to determine the driver and driven gears is to identify the gear that is connected to the power source, such as a motor or engine, as this gear would be the driver.
The gear(s) connected to this gear and turning as a result is the driven gear.
Another way is to observe the direction of rotation of the gears, the gear that is rotating clockwise is the driver and the gear which is rotating anticlockwise is the driven gear.

Describe these guidelines.
Answer:
1.A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2.A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
3.A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.
Explanation:
Here are three displacements, each in meters: d₁ = 7.61 +2.5) - 3.4k, d₂ = - 1.01 + 2.0 + 3.0k, and d3 = 4.01 +3.0 +2.0k. What is 7 = d₁ - d₂ + d3 ((a), (b) and (c) for î, j and k components respectively)? (d) What is the angle between 7 and the positive z axis? (e) What is the component of d along the direction of d2? (f) What is the component of d, that is perpendicular to the direction of d2 and in the plane of d, and d₂? 1
Answer:
a) The i-component of 7 is (7.61 + 2.5) - 3.4k = 7.61 + 2.5 - 3.4k
b) The j-component of 7 is -1.01 + 2.0 + 3.0k = -1.01 + 2.0 + 3.0k
c) The k-component of 7 is 4.01 + 3.0 + 2.0k = 4.01 + 3.0 + 2.0k
d) To find the angle between 7 and the positive z-axis, we need the dot product of 7 and the unit vector along the positive z-axis (0,0,1). The dot product is given by:
(7.61 + 2.5 - 3.4k)(0) + (-1.01 + 2.0 + 3.0k)(0) + (4.01 + 3.0 + 2.0k)(1)
And the angle between 7 and the positive z-axis is given by the following formula:
cos(theta) = (7.dot.unit_vector_z_axis) / (||7||.||unit_vector_z_axis||)
e) To find the component of d along the direction of d2, we need to find the projection of d on d2. The projection is given by the dot product of d and d2 divided by the square of the magnitude of d2.
f) The component of d that is perpendicular to the direction of d2 and in the plane of d and d2 is given by the vector subtracting the component of d along the direction of d2 from the original vector d
a) The i-component of 7 is (7.61 + 2.5) - 3.4k = 7.61 + 2.5 - 3.4k
b) The j-component of 7 is -1.01 + 2.0 + 3.0k = -1.01 + 2.0 + 3.0k
c) The k-component of 7 is 4.01 + 3.0 + 2.0k = 4.01 + 3.0 + 2.0k
d) To find the angle between 7 and the positive z-axis, we need the dot product of 7 and the unit vector along the positive z-axis (0,0,1). The dot product is given by:

A gear train has a ratio of 40/24 and the driving gear is turning 100 RPM.
What is the speed of the driven gear in RPM?
Answer:
S2 = 60 RPM.
Explanation:
Given the following data;
Gear ratio = 40/24 (T2 = 40 and T1 = 24).
Speed of driving gear = 100 RPM
To find the speed of the driven gear;
Mathematically, gear ratio in terms of speed (RPM) is given by this formula;
[tex] S_{1} * T_{1} = S_{2} * T_{2} [/tex]
Where;
S1 represents the speed of the driver gear.S2 represents the speed of the driven gear.T1 represents the number of teeth of the driver gear.T2 represents the number of teeth of the driven gear.Substituting into the equation, we have;
[tex] 100 * 24 = S_{2} * 40[/tex]
[tex] 2400 = 40S_{2} [/tex]
[tex] S2 = \frac {2400}{40} [/tex]
S2 = 60 RPM.
Therefore, the speed of the driven gear is 60 revolutions per minute.

Basically, a simple machine allows for the transformation of energy into work. The six simple machines are;
I. Inclined plane: gravitational potential energy to mechanical energy (kinetic energy). It is set at an angle and then used to lift an object.
II. Screw: kinetic energy to potential energy. It is held in position and then used to tighten two or more objects together.
III. Wheel and axle: gravitational potential energy to mechanical energy (kinetic energy). It comprises of two circular objects which aids in the motion of an object such as a car.
IV. Lever: gravitational potential energy to mechanical energy (kinetic energy). It comprises of a pivoted bar at a fixed point (fulcrum) that allows it to be used for lifting heavy objects.
V. Wedge: gravitational potential energy to mechanical energy (kinetic energy). It can be used to split objects into halves.
VI. Pulley: gravitational potential energy to mechanical energy (kinetic energy). It is made up of a wheel and rope which allows force to be multiplied such as in a drawing well.

A first class lever has a 180 lb. FR and 30 lb. effort force. The lever’s FE is located 6 ft from the fulcrum. What is the actual mechanical advantage of the system?
Answer:6
Explanation: To calculate the actual mechanical advantage (AMA) of a first-class lever, we use the following formula:
AMA = load/effort
In this case, we know that the load (FR) is 180 lb and the effort (FE) is 30 lb. So we can plug these values into the formula:
AMA = 180 lb / 30 lb
AMA = 6
So the actual mechanical advantage of the system is 6, meaning that for every 1 lb of effort applied, the load moves 6 lbs.
The load distance is given as 6 ft, but it is not used to calculate the AMA in this case. The AMA is calculated only from the ratio of load and effort forces.
