Explain the controlling force diagram of a spring controlled governor. If in a spring controlled governor, the weight of each governor ball is 40 N. The extreme radii of rotation of balls are 10 cm and 17.5 cm. The corresponding controlling forces at these radii are 250 N and 400 N respectively. Determine (a) General equation for controlling force (b) Coefficient of insensitiveness at a radius of 15 cm Solution please 🥺

Derive the expression for stiffness of the compression for a Hartnell governor. Also obtain its value with the following data: w = 1.4kg, r1 = 11.25cm , r2 = 7.5cm N1 = 318 rpm, N2 = 300 rpm. The axis of rotation is 9 cm from the fulcrum of the bell crank lever, the bigger and smaller arms of the lever are 11.25 cm, and 7.5 cm respectively. Sir questions bta do plzz
