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 is transmitted through the shaft and delivered to the belt on pulley B. Assume the belt tension on the loose side at Bis 15 percent of the tension on the tight side. For the steel countershaft shown in the figure below, find the slope of the shaft at each bearing. Use superposition...

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 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.

Two slender links, AC and BC, extend from a wall and support a pulley at C. A cable, tied at D, passes over the small pulley at C and experience an 80-lb force at its free end E. If the pulley is frictionless and of negligible determine the forces developed in members AC and BC. An inextensible (cannot stretch) cable AC and spring CB are originally horizontal. A 100-N weight is attached to point C, and the system is...
AC generator connected across an inductor
The output voltage of an AC generator is given by Δv = (1.18 ✕ 102 V)sin(31?t). The generator is connected across a 0.500 H inductor. Find the following.(a) frequency of the generator Hz(b) rms voltage across the inductor V(c) inductive reactance Ω(d) rms current in the inductor A(e) maximum current in the inductor A(f) average power delivered to the inductor W(g) Find an expression for the instantaneous current. (Use the following as necessary: t.)i=2.42·sin(31πt) (h) At what time after t = 0 does the instantaneous current first reach 1.00 A? (Use the inverse sine function.) Your response differs...
