Find the resultant of the force system on the body OABC as shown .find the points where the resultant will cut the X and Y axis?
Explanation:
the resultant force =
[tex] \sqrt{} {x}^{2} + {y}^{2} [/tex]
A resultant force is the single force and corresponding torque that are produced when adding vectors to a system of forces and torques acting on a rigid body.
What are the resultant of the force system on the body?R = A + B. Instance 2 To create the resulting vector, two vectors facing the opposite direction are subtracted from one another. Here, the vector B is pointing in the opposite direction of the vector A, and the resulting vector is called R.
A force system is a group of forces that interact at specific locations (may also include couples). Therefore, the collection of forces shown on any free body diagram is a force system. A group of forces is simply referred to as a force system.
Therefore, When an item is under the influence of two or more forces, the combined force can be calculated by adding up the separate forces.

In a hydroelectric power plant, 65 m3/s of water flows from an elevation of 90 m to a turbine, where electric poweris generated. The overall efficiency of the turbine–generator is84 percent. Disregarding frictional losses in piping, estimate the electric power output of this plant.
Answer:
Electric power output of this plant is [tex]48.192\times 10^{6}\,W[/tex].
Explanation:
From First Law of Thermodynamics we understand that hydroelectric power plant transforms mechanical energy from fluid into electric energy. The power output of this plant ([tex]\dot W[/tex]), measured in watts, is determined by this expression, which is derived from definition of mechanical energy and energy efficiency:
[tex]\dot W = \eta \cdot \rho\cdot g\cdot H \cdot \dot V[/tex] (1)
Where:
[tex]\eta[/tex] - Energy efficiency, no unit.
[tex]\rho[/tex] - Density, measured in kilograms per cubic meter.
[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.
[tex]H[/tex] - Fluid column, measured in meters.
[tex]\dot V[/tex] - Volume flow, measured in cubic meters per second.
If we know that [tex]\eta = 0.84[/tex], [tex]\rho = 1000\,\frac{kg}{m^{3}}[/tex], [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], [tex]H = 90\,m[/tex] and [tex]\dot V = 65\,\frac{m^{3}}{s}[/tex], then the estimated electric power output of this plant is:
[tex]\dot W = (0.84)\cdot \left(1000\,\frac{kg}{m^{2}} \right)\cdot \left(9.807\,\frac{m}{s^{2}} \right)\cdot \left(90\,m\right)\cdot \left(65\,\frac{m^{3}}{s} \right)[/tex]
[tex]\dot W = 48.192\times 10^{6}\,W[/tex]
Electric power output of this plant is [tex]48.192\times 10^{6}\,W[/tex].

At a certain location, wind is blowing steadily at 7 m/s. Determine the mechanical energy of air per unit mass and the power generation potential of a wind turbine with 80-m-diameter blades at that location. Also determine the actual electric power generation assuming an overall efficiency of 30 percent. Take the air density to be 1.25 kg/m3.
Answer:
Explanation:
From the information given;
The velocity of the wind blow V = 7 m/s
The diameter of the blades (d) = 80 m
Percentage of the overall efficiency [tex]\eta_{overall} = 30\%[/tex]
The density of air [tex]\rho = 1.25 kg/km^3[/tex]
Then, we can use the concept of the kinetic energy of the wind blowing to estimate the mechanic energy of air per unit mass by using the formula:
[tex]e_{mechanic} = \dfrac{mV^2}{2}[/tex]
here;
m = [tex]\rho AV[/tex]
= [tex]1.25 \times \dfrac{\pi}{4}(80)^2 \times 7[/tex]
= 43982.29 kg/s
∴
[tex]W = e_{mechanic} = \dfrac{mV^2}{2}[/tex]
[tex]= \dfrac{43982.29 \times 7^2}{2}[/tex]
[tex]= 1077566.105 \ W[/tex]
[tex]\mathbf{ =1077.566 \ kW}[/tex]
The actual electric power is:
[tex]W_{electric} = \eta_{overall} \times W[/tex]
[tex]W_{electric} = 0.3 \times 1077.566[/tex]
[tex]\mathbf{W_{electric} =323.26 \ kW}[/tex]
Which is the main material in a solar cell?
You have discovered an element that is a poor conductor of electricity, has a low melting point, and is a gas at room temperature. How would you classify this element?
Answer:
All nonmetallic elements are generally poor conductors of heat and electricity. There are only 17 nonmetallic elements, while more than 75 percent of the known elements are either pure metals or metalloids, which are better conductors of heat and electricity to a varying degree.
Explanation:
A 100-mm-long strip of metal is stretched in two steps, first to 200 mm and then to 400 mm. Show that the total true strain is the sum of the true strains in each step; in other words, the true strains are additive. Show that, in the case of engineering strains, the strains cannot be added to obtain the total strain.
Answer:
Kindly check the explanation section.
Explanation:
Determine the strain in units in both steps.
For step one, strain = [ final length - Initial length]/ initial length = 200 - 100/ 100 = 1 unit.
For step two, the strain = final length - Initial length]/ initial length = 400 - 200/ 200 = 1 unit.
Total strain for the two steps = 1 unit + 1 unit = 2 units.
Estimation using single step is given below;
400 - 100/ 400 = 0.75.
It can be shown from above that the Engineering strength is Addictive.
The next thing to do is to determine the true strength. This is how it can be proved that the strength is Addictive or not.
b1 + b2 = (200 - 100/100) + (400-200/ 200)
b1 + b2 = 1 + 1 = 2.
b(total) = 400 - 100/100 = v2 - v1/v1.

Why is using the proper joining technique important? What could go wrong if the wrong joining technique is used?
Answer:
Explanation:
Using the proper technique is incredibly important because it prevents the materials being joined from breaking and/or causing an accident. If the wrong joining technique is used the materials may not hold in place and come apart easily instead. Also, some joining techniques are not meant for some materials and may instead cause the material to become weak and brittle causing it to break apart almost immediately.
Joining describes a technique which is used to merge two or more independent materials together. The use of wrong joining technique or procedure could result in accident.
In engineering construction, the need to join materials together is always needed for so many reasons. Hence, depending on the materials to be merged, welding, soldering and some other techniques may be employed.
Therefore, wrong or inadequate joining may cause these parts to split or breakup, hence causing severe casualty.

Life cycle assessments are used by various industries to identify and evaluate the total energy impacts of their products and services.
True or False?
Answer:
True.
Explanation:
A product life cycle can be defined as the stages or phases that a particular product passes through, from the period it was introduced into the market to the period when it is eventually removed from the market.
Generally, there are four (4) stages in the product-life cycle;
1. Introduction.
2. Growth.
3. Maturity.
4. Decline.
Life cycle assessment (LCA) also known as life cycle analysis can be defined as an environmental management technique which is typically used by industries to assess, monitor and analyze the impact of the various stages of the life-cycle of their products, systems, processes or activities and services on the environment i.e the cradle to grave impacts.
Generally, life cycle assessments requires a thorough evaluation of the raw materials and energy that are being used in the manufacturing process of a product or service, as well as determining the various emissions into the environment respectively.
For example, in the manufacturing process of a product, life cycle assessment evaluates the impact of the product from raw material extraction (cradle) to production (finished product), distribution, use, and the disposal of the product (grave).
Hence, life cycle assessments are used by various industries to identify and evaluate the total energy impacts of their products and services.
