13-34 A compound reverted gear train is to be designed as a speed increaser to provide a total increase of speed of exactly 40 to 1. Use spur gears with a 20° pressure angle and a diametral pitch of 6 teeth/in. (a) Specify appropriate numbers of teeth to minimize the gearbox size while avoiding the interference problem in the teeth. (b) Determine the gearbox outside dimension Y, assuming the wall thickness of the box is 0.75 in, and allowing 0.5 in clearances between the tips of the gear teeth and the walls. Problem 13-34

How do you know that it is -1.2? What determines the sign?
(b) A differential element on the bracket as shown in Figure 1 is subjected to plane strain that has the following components: ex = 150µ, ey = 200µ, yxy = -700µ. By using the strain transformation equations, determine: - (i) The equivalent in-plane strains on an element oriented at an angle 0 = 60° counterclockwise from the original position. (ii) Sketch the deformed element within the x' – y' plane due to these strains. (iii) The stresses on the oriented planes in (I) where the value of elasticity, E = 200 GPa and Poisson's ratio, v = 0.32. (iv) Give your comments on those stresses in (iii) in terms of elastic limit/failure if the material's yield strength in tension/compression is 250 MPa and in shear is 90 MPa.
The cross-section at C is annular, having an outer diameter of 25mm. The 1200 N forces are applied and the normal stress in the bone at point C is determined to be 3.80 MPa. Calculate the inner diameter of the bone cross section at C.
