Q2/ In the proell governor shown in figure below, the arm ABC is formed in one piece. Each ball has a mass of 1.8 kg and the effect of friction is equivalent to a force of 9N at the sleeve. AB = 150 mm, BC = 50 mm, and BD = 150 mm. Find the magnitude of the central load on the sleeve, if the governor is to rise to its mean position as shown in the diagram when the speed is 120 r.p.m, the portion BC of the lower arm then being vertical. The gravitational effect of the balls must be taken into account. 25 mm B 225 mm A 25 mm

A simple log bridge in a remote area consists of 2 parallel logs with planks across them. The log has an average diameter of 300 mm. A truck moves slowly across the bridge, which spans 2.5 m. Assume that the weight of the truck is equally distributed between the 2 legs. Because the wheel base of the truck is greater than 25 m. Only 1 set of the wheels is on the bridge at a time. Thus, the wheel load on one log is equivalent to a concentrated load acting at any position along the span. In addition, the weight of 1 log and the plank it supports in equivalent to a uniform load of 65 kN/m acting on the log. 1. Determine the max permissible wheel load W based upon the allowable bending stress of of 7MPa. 2. Determine the max permissible wheel load W based upon the allowable shear stress of of 0.75MPa. 3.

3. For protection, the barrel barrier is placed in front of a bridge pier. The relationship between the force and deflection of the barrier is as given in the plot. For a car weighing 4000 lb and travelling at 50 mph as it first impacts the barrier, find the penetration of the car into the barrier. Note: One interpretation of Up = fF.dr is that work is the area under the force-deflection curve. F (lb) F=90(10)³x¹/2 -x (ft)
