Question: A vertical force P exerted on a lever A B holds a 2 0 - k g mass from falling, as shown in Fig. 9

A vertical force P exerted on a lever AB holds a 20-kg mass from falling, as shown in Fig. 9-43. The coefficient of friction between the lever and the 300-mm drum is 0.25. Neglect the mass of the drum and lever and determine the force P to hold the mass
A vertical force P exerted on a lever A B holds a
