Question

0.3m ACME lawn rollers is updating its design of lawn rollers. They would like to make sure that the drum does not slip and damage the grass when it is pushed. Determine the maximum force F before the drum slips when 0-30°. The static coefficient of friction between the grass and roller is us 0.3. Assume that the mass of the roller handle can be neglected. The mass of the cylindrical portion of the roller is 40 kg. and it has a radius of gyration, kG - 0.20 m. If the maximum push force a user puts on the handle will exceed the calculated F, how should θ be changed? Explain your answer.
