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.

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point.the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.
