Part (a) Write an expression for F, just as the crate starts to move using the sum of the forces in the x-direction in terms of the variables F and 02. F, = F, cos(01) + F2 cos(02) Part (b) Write an equation for the sum of forces in the y-direction when the crate just starts to move using the specified coordinate system answer in terms of the variables F1, F2, 01, and 02. EF, = F, sin(01) - F2 sin(02) Part (c) Combine these two equations to develop an expression for tan(02) in terms of F, F1, F2, and 0,. Remember that the crate does n along the y-direction. tan(02) = F1 sin(0,)( F, - F1 cos(01))
