A helical coil spring is to be made of A227 steel (hard-drawn) wireof 4-mm diameter. The free length of the spring should be 80 mm and itsends will be plain. (1)Design the coil diameter of the spring so that it deflects by 5 mm from its free length under a compressive force of 50 N.(2)Determine if the spring will fail by yielding when it is compressed to its solid length. Assume that the shearyield strength of the material is 55% of its tensile strength.

What is the main objective of using reheat rankine cycle?

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?

What is the correct way to measure the overall length of a boat? measure from the tip of the bow to the highest point on the gunwale. measure from the tip of the bow in a straight line to the stern of the boat. measure from the tip of the bow in a straight line to the back seat. measure from port to starboard at the boat's widest point.
