Question
Determine the range of the force P required to keep the system stationary. P acts parallel to the
ground, and the coefficients of static friction at the contacting points are ?? = 0.2, ?? = 0.3,
and ?? = 0.4. Both the 100-kg roller and 40-kg hollow cylinder have a radius of 150 mm (use
g = 9.81 m/s2).
