5Q. The plate is moving at 0.6 mm/s when the force applied to the plate is 4 mN. If the surface area of the plate in contact with the liquid is 0.5 m², determine the approximate viscosity of the liquid, assuming that the velocity distribution is linear. The thickness of the liquid layer is 4 mm. 0.6 mm/s 4 mm 4 mN

A circular nylon [E = 8 GPa; ν = 0.35; α = 29 ×10-6/°C] disk with a circular hole in its center is shown. At an initial temperature of Ti = 22°C, the outer diameter of the disk is D = 210 mm, the diameter of the central hole is d = 55 mm, and the thickness of the disk is t = 24 mm. At a final temperature of Tf = 46°C, determine:(a) the change in diameter Δd of the central hole (assume an increase Δd as positive, otherwise as negative).(b) the change in thickness Δt of the disk (assume an increase Δt as positive, otherwise as negative).(c) the normal strain in the circumferential direction around the outside of the disk.

Q2) Figure Q2 shows a 30-kg block is connected to block B through a frictionless pulley. The coefficient of static friction for the contact surfaces is 0.35. (i) (ii) Determine the mass value of block B when the impending motion of block A is down the plane. Determine the mass value of block B when the impending motion of block A is up the plane. 20⁰ А μs=0.35 Figure Q2 B

A steel fence wire 3.5 mm in diameter is stretched between rigid end posts with a tensile stress of 139.07 MPa when the temperature is 32°C. The proportional limit of the wire is 276 MPa. E = 207 GPa. Compute the temperature drop (change in temperature) that could occur without causing a permanent set in the wire. a =0.0000117 /°C. (Do not include the sign). Hint: The material will not experience permanent set as long as the stress experienced does not exceed the proportional limit.
