A 1520-N crate is to be held in place on a ramp that rises at 30.0° above the horizontal. The massless rope attached to the crate makes a 22.0° angle above the surface of the ramp. The coefficients of friction between the crate and the surface of the ramp are ėk= 0.450 and" ės= 0.650. The pulley has no appreciable mass or friction. What is the maximum weight w needed to hold this crate stationary on the ramp?
