Are there any pictures which go with this problem? Any other information which you may not have included?KingKell said:Homework Statement
A grinder consists of a 6.01 kg steel block on a 1.46 m long arm that spins around a table. If the angular acceleration is -1.62 rads/s2, what is the coefficient of friction between the steel block and the table?
I'm having trouble with attempting the question, especially drawing free body diagram for this problem.

Please don't delete parts of the HW template.
The steel block on the grinder weighs 6.01 kg.
The arm of the grinder is 1.46 meters long.
The mass of the entire grinder will depend on the weight of the steel block and the weight of the arm itself. If the arm is negligible in weight compared to the block, then the mass of the grinder would be approximately 6.01 kg. However, if the arm is significantly heavier, then the mass of the grinder would be slightly more than 6.01 kg.
The torque applied to the grinder can be calculated by multiplying the weight of the steel block by the length of the arm. In this case, the torque would be approximately 8.78 Nm (6.01 kg x 1.46 m = 8.78 Nm).
The amount of force needed to move the grinder will depend on various factors such as the friction between the grinder and the surface it is resting on, the weight distribution of the grinder, and the force applied to the arm. It is not possible to determine the exact force needed without additional information.
