the 1-Mg forklift is used to raise the 750-kg crate with acceleration of 2 m/s. deterimine reaction exerted by the groung on the airs of wheel at A and B.
No heat interactions with the environment are allowed. You do not need to describe the details of the process that produces the maximum work, but you do need to describe the final state of the blocks fully.
Determine the resulting change
A jack-screw has a handle 35 inches long and a pitch of 7/32 inches. If a pull of 15 lbs. is required at the end of the handle to lift a 3,000 lbs.
Two flat, rectangular plates with a lateral dimension w*l lie parallel, one above the other, a distance h apart. The gap between them is filled with molten polymer.
Design life is 9630 hours, rotating at 250 rpm, load of 880 lbs, what is the basic design load rating (assuming no axial loads)?
Solve the problem in the image. Do it step wise in detail. This question is from book "Fracture Mechanics - An Introduction - E. Gdoutos Springer (Page 74)"
Effect of pressure on temperature and density of air for an adiabatic process, The pressure is to be raised from atmospheric to 7 psi (4.83 bar). The process is adiabatic, and the volume is constant and unknown.
Refrigerant 134a leaves the evaporator as saturated vapor at 1.4bar and is heated at constant pressure to 20 degrees C before entering the compressor.
Plot the spectral blackbody emissive power of the sun versus wavelength in the range of 0.01 micro m to 1000 micro m?
A 12 Volt battery is charged by supplying 3 Amps over a period of 6 hours. What is the change of energy stored in the battery if the battery loses 400kJ of heat during charging.
Determine the heat transfer coefficient for laminar flow over this cylinder. First, at your discretion, select an available set of experimentally obtained data from the literature. Then, this would provide you with a set of Reynolds numbers.
Determine if the shaft has infinite fatigue life. If not, determine the number of cycles to failure. Also determine the safety factor for first cycle yield and draw a free body diagram, shear and moment diagrams, and graph the loads on the shaft..
