Question
A continuous countershaft carrying two 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. Solve in SI.
1. Find the preliminary diameter of the shaft from static considerations (Method 1) if the shaft material is steel
with Sy = 405-MPa and SF = 5. Bending moment and torque diagrams are provided in N, mm.
2. Calculate the critical rotation speed of the shaft if pulley A weighs 100-N and Pulley B weighs 150-N and the
weight of the shaft is included in the calculation. The shaft steel density is 7861-kg/m3 and the Elasticity
modulus is 200000-MPa. The shaft deflections at locations A (by pulley A acting alone) and B (by pulley B acting
alone) are given below:
