Pulleys C and D are attached to shaft AB, as shown. The shaft is supported on bearings at each end. The shaft rotates at a uniform speed. Pulley D is the driver and pulley C is the power take-off. The diameter of the shaft is 2 1 2 in. Calculate
a. the belt tension P3.
b. the maximum shear stress in the shaft.
At the instant specified the magnitude of the vertical component of the linear acceleration of the particle at the point B was A. 4.50 fps per sec. C. 7.50 fps per sec. B. 5.50 fps per sec. D. 9.0 fps per sec.
A steel microstructure contains 75% martensite and 25% ferrite; the composition of the martensite is 0.6% C. Using Figure 12-28,
A quantity of gas has an initial pressure of 2.72MN/m^2 and a volume of 5.6dm^3(l). It is expanded according to the law PV^1.35 = C down to a pressure of 340kN/M^2. Determine the final volume and work done.
Using the hydrostatic law dp/dz = -(rho)g and the ideal gas law p = (rho)RT, show that if the temperature of the atmosphere varies with height as T(z) = T_o - Bz, then the atmospheric pressure varies with height as p(z) = p_o(1-(Bz/T_o))^(g/(BR))
