For the simple gear train below, Gear A is the input gear and rotates at 2500 rpm. The number of teeth for each gear is as follows: NA = 60 Teeth, NB = 84 Teeth, NC = 36 Teeth and ND = 60 Teeth.Calculate the output angular velocity at Gear D (ωD).Give your answer in rads-1 to the nearest radian. Gear D is the output gear for the simple gear train shown below.

Industrial Maint.   What are the direction and speed of the driver gear (D1) in Figure 6-40 if the driven gear (D2) is a 2 in. gear, D1 is a 12 in. gear and D2 is rotating at 1248 rpm (CW)? see picture

Technician A says that if a single idler gear is used to obtain reverse gear, its size and number of teeth must be used to calculate gear ratios. Technician B says that an idler gear is often used for reverse gear because it causes the output shaft to rotate in the reverse direction of the input shaft. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor B
