Laboratory tests on human teeth indicate that the area effective during chewing is approximately o.25cm² and that the tooth length is about 1.1cm. if the applied load in the vertical direction is 880N and the measured shortening is 0.04 cm, determine Young's modulus

Q.1 Two plates of size 100 mm by 50 mm are separated with a 1 mm thick fluid in between. The top plate is moving to the right with a constant velocity of 10 m/s in response to a force of 3 N. The bottom plate is stationary. Determine the viscosity of the fluid by assuming a linear velocity distribution.
