The square-threaded screw with a pitch of 10 mm and a mean radius of 18 mm drives a gear that has a mean radius of 75 mm. The static and kinetic coefficients of friction between the gear and the screw are 0.12 and 0.06, respectively. The input torque applied to the screw is C0=10Nm. Assuming constant speed operation, determine the output torque C1 acting on the gear.
The coeffient of static friction between the uniform bar AB of weight W and the ground is 0.45. Find the smallest angle and the corresponding force P that would initiate simultaneous tipping and sliding of the bar.
A uniform plank is supported by a fixed support at A and a drum at B that rotates clockwise. The coefficients of static and kinetic friction for the two points of contact are as shown. Determine whether the plank moves from the position shown if (a) the plank is placed in position before the drum is set in motion; and (b) the plank is first placed on the support at A and then lowered onto the drum, which is already rotating.

The screw of the carjack has a pitch of 0.1 in. and a mean radius of 0.175 in. Note that the ends of the screw are threaded in opposite directions (right- and left-handed threads).

A triple-thread Acme-form power screw of 50 mm major diameter is used. The nut makes 1.5 turn per cm of axial travel. A force of 600 N is applied at the end of a 850 mm wrench used on the nut. The mean diameter of the collar is 90 mm. If the coefficient of friction at the thread and at the collar are 0.15 and 0.13, respectively. Determine the weight that is being lifted.
An elevator type lift is being designed to raise a load up to 5,000pounds between floors. Two square-thread lead screws, 1.5 inches in (major) diameter, are used for this application. Determine the torque required to raise this lift if the moving part of the elevator weighs 800 pounds and the coefficient of friction is assumed to be 0.15. For the elevator described, find the efficiency and power required if each lead screw is driven at 175 rpm. Verify if this is self locking.
A vertical power screw with double start square threads of 50 mm mean diameter and 11mm pitch is raised against a load of 10 kN by means of a hand wheel, the boss of which is threaded to act as a nut. A thrust collar, taking up the axial load,supports the wheel boss and has a mean diameter of 60mm. The coefficient of friction is 0.18for the screw and 0.16for the collar. If the tangential force applied by each hand to the wheel is 200 N, find suitable diameter of the hand wheel.
High-strength bolts are used in the construction of many steel structures. For a 1-in.-nominal-diameter bolt, the required minimum bolt tension is 51 kips. Assuming the coefficient of friction to be 0.30, determine the required couple that should be applied to the bolt and nut. The mean diameter of the thread is 0.94 in., and the lead is 0.125 in. Neglect friction between the nut and washer, and assume the bolt to be square-threaded.
