A 12-tooth external spur gear A, rotating clockwise, drives a gear B whose diametral pitch is 4. The ratio of the speed of gear A to gear B is 2 to 1. The tooth proportions are standard 14-12° brown and sharpe. (1) Placing the center of gear A on a vertical line above the center of B on the same vertical line show and give the diameters of the pitch circles, addendum circles, and dedendum circles. (2) Sketch in roughly enough of a tooth on each gear in contact at the pitch point and indicate the face of the tooth, the flank of the tooth and the pitch point.

please help

Help me with this question please! Thanks!

Problem 2. A compound gear train as shown in the following figure, Gear 1 has 24 teeth and Gear teeth of diametral pitch of 4. Gear 3 has 30 teeth and Gear 4 has 50 teeth of diametral pitch of 3. Gear 1 turns 12 rpm in clockwise direction. 2 has 70 (a) Computer the speed and direction of the shaft carrying Gear 4. (b) Find the torque at Shaft c if the input horsepower at Shaft a is 50? Shaft b Shaft c Shaft a Gear 1 Gear 2 Gear 3 Gear 4

A driving wheel of a gear has a radius of 20 cm and driven gear has 9 teeth along its circumference. If the driven wheel makes 5 rotation for every one rotation of the driving wheel. Calculate the rear ratio and diametral pitch

Use the right formula. A 20 degree-pressure-angle, 22-tooth spur gear has a diametral pitch equal to 5. Calculate the dedendum in mm
