Compute the torques produced by the following forces. Be sure to indicate whether the torque action is CW or CCW.
A uniform ladder of length L and weight w is leaning against a vertical wall. The coefficient of static friction between the ladder and the floor is the same as that between the ladder and the wall. If this coefficient of static friction is u, = 0.385, determine the smallest angle the ladder can make with the floor without slipping. 52.4 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.°
