A tendon-operated robotic hand can be implemented using a pneumatic actuator. The actuator can be represented by

G(s) = 1000/(s + 100)(s + 10)

Use Matlab to plot the frequency response of G(j). Show the magnitude of G(j) and phase shift at = 10, 200, and 700.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
