A servomotor is connected to a forearm axis drive shaft without any reduction drive components. The maximum weight of the part and gripper at the end of the forearm is 55 pounds and the forearm length is 65 centimeters. Determine the motor torque in foot-pounds required to prevent the forearm from rotating under the gripper and part weight.
Define your system to be the gas in the cylinder, and calculate the work transferred from the surroundings to the system from this expansion. Note that the pressure will change as the expansion takes place.
determine the expressions for attractive and repulsive energies, EA and ER as a functions of r where r is in nm and E is in eV.
