Make the following changes to the
original problem:
- The static coefficient of friction in the "Y" direction (the direction of the yellow arrow) is mu_y = 0.8
- The static coefficient of friction in the "X" direction (the direction of the blue arrow) is mu_x = 0.2
- The static coefficient of friction varies
linearly with theta from mu=0.2 in the "X" direction to mu=0.8 in the "Y" direction as theta goes from zero (X direction) to pi/2 (Y direction).
Now find the value of Fx at which the block begins to slide.
