An object of mass M rests on a horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass m. There is static friction between the horizontal surface and mass M.
The coefficient of static friction is 0.75 and M=15. kg.
The string and pulley are ideal and massless. Use g=9.8 m/s2.
What is the maximum value of mass m that can be hung from the strong so that mass M does not slide on the surface?
mass m is the pulling force, mg
M is being pulled, a maximum of Mg*mu
