What does it mean when a steel cable is required to have a factor of safety of at least 5 against its ultimate load? This is a solid mechanics question involving a rigid bar pinned at one end and held up by steel cables with a load acting downward on the rigid bar.
Calculate the specific heat at constant pressure, and specific heat at constant volume for propane which is compressed at the following inlet condition;
An iceberg with specific gravity (SGice) of 0.92 is partially submerged in seawater whose specific gravity is SGw= 1.025. Determine the relative volume of the iceberg that appears above the surface of the sea.
An air conditioner in the airport of Timbuktu runs a cooling system using R-410a with a high pressure of 1500 kPa and a low pressure of 200 kPa. It should cool the desert air at 45 degrees C down to 15 degrees C. Find the cycle COP. Will the syste..
If the maximum temperature in the cycle is not to exceed 2200 K, determine the thermal efficiency and the mean effective pressure.
Sketch the fully annotated velocity triangles for a Parsons turbine stage. Use your sketch to show that the specific work produced per stage is given as w_stage = (C_b)^2 [1 + 2(f/C_b)(cot(B_1))].
At the exit, the pressure is 113 kPa and the temperature is 69 degrees C. Determine the mass flow rate, the exit velocity and the area of the exit.
Describe the machinability evaluation criteria, is it a quantitative or qualitative evaluation and describe the High Speed Machining of Steel/Iron or Aluminium
A first class lever in static equilibruim has a 50 lb resistance force and 15 lb effort force. The lever's effort force is located 4 ft from the fulcrum. What is the actual mechanical advantage of the system?
