Consider the centrifugal clutch above that comprises of four ‘shoes’ symmetrically attached to the ‘spider’. Each shoe with its friction lining has a mass of 275 grams and is attached by means of a linear mechanical spring with a stiffness value of 7.5 kN/m. The coefficient of friction of the material attached to the shoes is 0.35. The centre of mass of each of the shoes is at a radius of 95 mm from the shaft centres in the rest position shown above and has a clearance distance of 9 mm to the outer drum. The outer drum has a wall thickness of 4 mm. Question 1 a. Determine the engagement speed of the centrifugal clutch. You should provide your answer in RPM (revolutions per minute) and rounded to the nearest whole value of RPM. b.

The 136-kg industrial door with mass center at G is being positioned for repair by insertion of the 6° wedge under corner B. Horizontal movement is prevented by the small ledge at corner A. The coefficients of static friction at both the top and bottom wedge surfaces are 0.58. Calculate the rightward force P' which would remove the wedge from under the door. Assume that corner A does not slip for your calculation of P, but then check this assumption; the coefficient of static friction at A is 0.58.
