- Hi please help me with this problem, Thank youarrow_forwardDesign a pair of plastic gears to drive a small band saw, using the following data: The input is from a 0.5hp electric motor rotating at 1160 rpm. The pinion is mounted on its 0.75 in diameter shaft. The gear is rotating at 250 rpm. For design purposes, consider taking Np=18 (number teeth in pinion) and Pd = 12 (diametral pitch). In this case, the acceptable number of teeth in the gear should be: NG=58 teeth NG = 93 teeth NG = 84 teeth NG = 70 teetharrow_forwardplease send handwritten solution Q4 part aarrow_forward
- If the shafts on the two gears shown in this figure had the same diameter, but were made of different materials, which shaft should be made of the stronger material to avoid breakage? (Hint: The torque exerted on each shaft must be the same as the torque on the gear to which it is attached.)arrow_forwardExplain various types of Gear.
