Required information The shaft shown in the figure is machined from AISI 1040 CD steel. The shaft rotates at 1600 rpm and is supported in rolling bearings at A and B. The applied forces are F₁ = 1600 lbf and F2 = 640 lbf. A steady torque of 1600 lbf-in is being transmitted through the shaft between the points of application of the forces. ↑ i 3 in- -10 in- F₁ ↑ in F₂ -10 in- All fillets in R. -8 in inៗ → p'in 3 in in B -3 NOTE: This is a multi-part question.

A gear reduction unit uses the countershaft shown in the figure. Gear A receives power from another gear with the transmitted force FA applied at the 20° pressure angle as shown. The power is transmitted through the shaft and delivered through gear B through a transmitted force Fg at the pressure angle shown. For the steel countershaft shown below, assume the bearings have a maximum slope specification of 0.062° for good bearing life. Check wether the shaft dia below meets the requirement.
