The upside-down steel A frame shown in the figure is to be bolted to steel beams on the ceiling of a machine room using ISO grade 8.8 bolts. This frame is to support the 40-kN radial load as illustrated. The total bolt grip is 48 mm, which includes the thickness of the steel beam, the A-frame feet, and the steel washers used. The bolts are size M20×2.5. What tightening torque should be used if the connection is permanent and the fasteners are lubricated? What portion of the external load is taken by the bolts? By the members?
A rigid bar of mass m and length L is released from rest in the horizontal position. What is the rod's angular velocity when it has rotated through 90°?
Two collars C and D move along the vertical rod as shown. Knowing that the velocity of collar C is 50 in/s downward, find the instant centers of all three bars, the angular velocity of AB, the velocity of collard D.
Treat the locomotive as a particle and assume that the railroad tracks are rectilinear and horizontal.
