Homework Statement
The cylinder with mass 200[kg] and radius 0.8[m] tries to climb a 0.3[m] high edge with a force F exerted at an angle of 30^{0}. what's the force and what's the minimum force for the cylinder to climb
Homework Equations
Moments: F_{1}L_{1}=F_{2}L_{2}
The Attempt at a Solution
The weight balances the the force, i made moments around the edge and got a true answer F=1670[N], but i don't understand the second question, about the minimum force, and it's about 766[N]
