The mass of the central load is 15 kg, the mass of each ball is 2 kg and friction of the sleeve together with the resistance of the operating gear is equal to a load of 25 N at the sleeve. If the limiting inclinations of the upper arms to the vertical are 30° and 40°, find, taking friction into account, range of speed of the governor.
Q. The effective mean diameter of contact surfaces of a cone clutch is 76 mm. The semi-angle of the cone is 16 degree and the coefficient of friction is 0.3. Assuming uniform rate of wear, determine the torque required to produce slipping of the clutch, if the axial force applied is 200 N. The clutch connects an electric motor running at a uniform speed of 1200 r.p.m to a flywheel which is stationary. The moment of inertia of the flywheel is 0.25 kg-m2. Calculate the time required to attain the full speed and also the energy lost in slipping of the clutch.
Problem 8 Another Gear Two disks are connected to one another with a belt as shown. Both disks have mass m but the larger one has radius 4R and the smaller has radius R. The larger disk is powered by a motor that produces a constant torque, To, in the counter- clockwise direction. (a) By using the rotational equivalent of Newton's laws on the larger disk show that the difference in the tension at the top with the tension at the bottom is: Tto - Thot 1 4R (TO - 2m Ra), where a is the linear accleration of the elt. (b) Do the same (find Ttop - Tbot) with the smaller disk. (c) Use your two expressions to find the gular acceleration of the smaller disk. You answer should have m, R, and To in it only. (Careful, the sr aller disk does not have the same angular acceleration as the larger one).
