Mech. Engg. Dept. 4th year 2022-2023 Solar Energy Spring course MEC364 Dr. Mahmoud U. Jasim Review/Recap Sheet Q1- Answer with true or false and rewrite the false statements completely in correct form, otherwise no mark will be put on the false statements. 1 2 To represent a location on earth surface you need to define its altitude and longitude angles. 3 Solar zenith and solar incidence angles have the same value for horizontal surface. At sunset time the value of solar altitude angle is maximum. 4 The angle which represents the inclination of a given surface is the zenith angle 5 6 7 8 When the absolute value of sun-wall azimuth angle exceeds 90' this means that the sun rays are reaching the receiving plane. The solar irradiance and the solar irradiation have the same physical meaning. In the case of clear sky weather, the beam solar irradiation on a horizontal surface is less than the diffused irradiation. The total solar radiation received by a tilted surface is the same as that…

I Review Learning Goal: To be able to find the center of gravity, the center of mass, and the centroid of a composite body. Part A A centroid is an object's geometric center. For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the bodyng the weighted average Find the area of the body. (Figure 1) Express your answer numerically in feet squared to three significant figures. into regular shaped segments, and then by calculating i of the segments' centroids.An object is made from a uniform piece of sheet metal. The object has dimensions of a = 1.55 ft , where a is the diameter of the semi- circle,b = 3.74 ft, and c = 2.35 ft . A hole with diameter d = 0.750 ft is centered at (1.26, 0.775). > View Available Hint(s) Vol AEO It vec ? A = ft? Submit Part B Find a, the a-coordinate of the body's centroid.

If monthly payments on this loan are $432.61, how many months will it take for Sallie to repay the entire loan?

A dust particle is suspended in the air (floating due to a small updraft and its own low mass) when a powerful loudspeaker plays a very low note (2 Hz so it can’t be heard but you can actually see the speaker move!). How will the dust particle move as a result of the speaker 
being turned on? Question 3 options:   A)  The dust particle will move up and down.   B)  The dust particle will be pushed across the room.   C)  The dust particle will move in a circular path.   D)  The dust particle will move side to side.

This is the complete question and not a writing assignment. Make sure for this problem you list the following: a. Known: State briefly what is known about the problem. b. Schematic: Draw a schematic of the physical system or control volume. c. Assumptions: List all necessary assumptions used to complete the problem. d. Properties: Identify the source of property values not given to you in the problem. e. Find: State what must be found. f. Analysis: Start your analysis with any necessary equations. Develop your analysis as completely as possible before inserting values and performing the calculations. Draw a box around your answers and include units and follow an appropriate number of significant figures.

C)If both cyclists have 170 mm cranks on their bikes, what will be the mechanical advantage (considering only the movement of the feet with a constant force for walking and riding), in percent, that each rider will have achieved over walking the same distance? (This can be found by dividing the distance wallked by the distance the feet move in riding.)

Case Study: Paula’s Pain Paula has worked for Brindle Corporation for 3 years.  During this time, she has worked as a machine operator/cell leader in various work cells.  Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel.  These tubes get a hole punched in them, a flange welded on, and burrs ground off.  The pipe then gets placed into a gage to check that it was made correctly.  (The tubes weigh about six pounds.) Paula has been performing the welding operation.  She leans into the machine and loads the part into a fixture then positions the flange.  Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position…

Explanation it correctly not use excel Q)land development company is considering the purchase of earth-moving equipment. This equipment will have an estimated first cost of $163,000, a salvage value of $65,000, a life of 10 years, a maintenance cost of $40,000 per year, and an operating cost of $420 per day. Alternatively, the company can rent the necessary equipment for $1030 per day and hire a driver at $180 per day. If the company’s MARR is 15% per year, how many days per year must the company need the equipment in order to justify its purchase? The company must need the equipment ____ days per year in order to justify its purchase.

Dynamics

Mechanical energy also known as motion energy. It is one of the only types of energy that is easy to see. It's describes how an object, or a system moves based on its position or motion. Give one example of engineering design around you that have mechanical energy such as kinetic energy and potential energy. Based on the example given, in your own word, а) explain how the kinetic energy change into the potential energy or vice-versa. b) describe the connection between the concept of power and work. c) how to ensure your design produce more power. Provide some calculation to support your answer. d) describe how the conservative force effect the system in the example given.
