Perform a graphical force analysis, including friction of the mechanism of Problem 9.6 with force
F
₂
= 0 . The coefficients of friction all equal 0.2, and the bearing radii are 0.3 in at and 0.5 in at B, C, and The crank rotates clockwise. Determine the torque
T
₁
required for static equilibrium.

Problem 9.6

Determine the required input torque
T
₁
for static equilibrium of the mechanism shown in Figure P9.6. Forces
F
₂
and
F
₃
have magnitudes of 20 lb and 10 lb, respectively. Force
F
₃
acts in the horizontal direction.
