Determine the magnitude and location of the resultant of the force systems shown
A horizontal force of 100 N is required to start a 40-kg block sliding along a horizontal sur- face. What is the coefficient of static friction?
Determine the mass of a block if a force of 25 N is required to start it sliding on a horizontal surface (μ = 0.33).
Determine the mass m that can be lifted by a rope with three-quarters of a turn around a fixed horizontal shaft (μ = 0.3) if a force of 15 kN is applied to its other end.
