Q2. In a spring loaded governor of the Hartnell type, the mass of each ball is 5 kg and the lift of the sleeve is 50 mm. The speed at which the governor begins to float is 240 rpm, and at this speed the radius of the ball path is 110 mm. The mean working speed of the governor is 20 times the range of speed when friction is neglected. If the lengths of ball and roller arm of the bell crank lever are 120 mm and 100 mm respectively. If the distance between the center of pivot of bell crank lever and axis of governor spindle is 140 mm, determine the initial compression of the spring. If friction is equivalent to a force of 30N at the sleeve. *

Consider a column bean under compression. A load P is applied at the upper end.Both ends have pinned boundary conditions. As you answer the following questions, you must explain each step, so you can show that you understand each step. You must also be concise and very brief.a.What is the critical load for this system. b.Assume that you now add a pinned supportis located a third of the way from the top of the column,and athird from the bottom of the column. These pinned supports prevent the column from laterally translating at the points of support. What is the new critical load of this system? Solve this problem in two very simple ways
