Extracted text: Question 5 Figure 5 shows a brake having one shoe with an applied force, F. Five seconds after the force is applied, the drum comes to a stop. During this time the drum makes 100 revolutions. Use the short- shoe approximation and an estimated coefficient of friction of 0.35. (a) Determine the magnitude of all forces including support reactions on the free body diagram. (b) How far above the drum centre would the arm pivot need be to make the brake de-energizing? Justify your answer. (c) How much work does the brake do in bringing the drum to a stop? 600 mm 500 mm F shoe R110 mm drum Figure 5 Variable Value Unit F 1,200 N ww 06
