A countershaft carrying two V-belt pulleys is shown in the figure. Pulley A receives power from a motor through a belt with the belt tensions shown. The power istransmitted through the shaft anddelivered to the belt on pulley B. Assume the belt tension on the loose side at B is 15 percent ofthe tension on the tight side.(a) Determine the tensions in the belt on pulley B, assuming the shaft is running at a constantspeed.(b) Find the magnitudes of the...
A countershaft carrying two V-belt pulleys is shown in figure 1 (dimensions in inches). Pulley A receives power from a motor through a belt with the belt tensions shown. The power is transmitted through the shaft and delivered to the belt on pulley B. Assume the belt tension on the loose side at B is 15 percent of the tension on the tight side. a) At the point of maximum bending moment, determine the principal stresses and the maximum shear...

I. The countershaft shown in the Fig Q1 has two spur gears mounted on it with teeth cut wi a 20 pressure angle. The shaft (grooved) is to be made of cold-drawn AISI 1040 steel havin Sut 779 MPa and S,-593 MPa, an elongation of 19% and HB-262. You are asked to size the shaft for safe operation according to DE-Elliptic criterion by using a factor of safety of 2.5 and a reliability of 99 percent. The stress-concentration factors for...

A countershaft, made of AISI 1035 CD steel, carrying two V-belt pulleys is shown in the figure. Pulley A receives power from a motor through a belt with the belt tensions shown. The power is transmitted through the shaft and delivered to the belt on pulley B. Assume the belt tension on the loose side at B is 25 percent of the tension on the tight side (F2 - 0.25 F) 1) Based on the equations for yielding conditions discussed...
