(Round the final answers to their nearest whole number.) The components of the reaction at A are: The components of the reaction at E are: ExE NT
The uniform 14-kg plate is welded to the vertical shaft, which is supported by bearings A and B. Calculate the magnitude of the force supported by bearing B during application of the 110-N-m couple to the shaft. The cable from C to D prevents the plate and shaft from turning and the weight of the assembly is carried entirely by bearing 110 Nm A 150 mm 70 mm 580 mm 180 mm 330 mm Answer: B kN The uniform 14-kg...

Given: The plate is subjected to the couples and forces shown (P = 0 N). The couple @ F is 42 N.m CCw and the couple @H is 40 N m CCW Find: The plate is to be held in place by one rivet that can resist a force but not a couple. Determine the location of the rivet hole along the line that passes through FG relative to the top of the plate (ED) such that the plate would...
help Under normal operating conditions, the electric motor exerts a torque on shaft AB. Pulleys B, C, and remove torques of 1.86 kN-m, 1.01 kN- m, and 0.67 kN-m, respectively. The bearing at E allows free rotation. Determine the maximum shear stress (in MPa) in section AB of the shaft if dAB=57.4 mm, doc=49.3 mm, dcd=45 mm, and dDE=37.8 mm. Hint: The internal torque from D to E is 0 kN-m and the supplied torque at the motor (point A)...
