3. Figure 4 shows a simplified schematic of the drive system of joint 4 of the PUMA 560. The torsional stiffness of the couplings is 200 Nt-m/radian each, that of the shaft is 400 Nt-m/radian, and each of the reduction gear pairs has been measured to have output stiffness of 2000 Nt-m/radian with its input gears fixed. Both the first and second reductions have n=4. Assuming the structure and bearing are perfectly rigid, a) What is the effective stiffness of gear 1 if the electric motor's shaft is locked? b) What is the effective stiffness of gear 3 if the electric motor's shaft is locked? c) What is the stiffness of the joint (i.e., when the motor's shaft is locked)?
