Considering fins with adiabatic tips, plot the fin efficiency, n,, as a function of length (from 1 to 20 cm) for fins made of Inconel 625 (a high temperature alloy of k = 20 W/m-K) with the following geometries: a. A rectangular straight fin with a width of 5 cm and a thickness of 0.5 cm b. A parabolic straight fin with a width of 5 cm and a thickness of 0.5 cm at the base. c. A rectangular pin fin (cylindrical) with a diameter of 1.8 cm. d. A triangular pin fin with a diameter of 1.8 cm at the base. For (a-d) assume that the convection coefficient is h= 8 W/m²-K in all circumstances. For better comparison, please plot all four cases in the same graph. Comment on the general rules for fin selection if you need to design a fin system.

Adjustable Link L m Pivot Pivot Screw 'B' Gripper In the drawing, arm A is being driven back and forth in the direction of the arrows. It is connected to a gripper by way of an adjustable link L, two horizontal bars and two vertical bars. Screw B is a shoulder screw secured to arm A, but allows the horizontal bar to pivot around it. If the shoulder screw B was lowered towards the end of arm A, and the stroke of arm A remained the same, the stroke of the gripper would: Arm 'A' 0 MIMINIA
