**Can someone please help me solve these problems step by step, thank you! 1. If a 12-inch diameter driving Gear A has 100 tooth which turns CCW with a torque of 200 ft-lb and 100 rpm is meshed with Gear B, 25 tooth, turn along with Gear C, 50 tooth as they are a compound gear and Gear D, 150 tooth meshed with C.
-->sketch and annotate the gear train.
-->what direction does gear ratio B, C, and D turn?
-->what is the gear ratio for B, C, and D?
-->what is the angular velocity for gears B, C, and D?
-->what is the torque for gears B, C, and D?
-->what is the diameter of gears B, C, and D?

2. In a pulley system, pulley A is moving 1000 rpm and has a diameter of 18inches. There are two pulleys with different sizes, B moving ot 1575 rpm and C moving at 1850 rpm attached on a single axle.
-->sketch and annote the pulley system.
-->what is the diameter of pulley B and pulley C?
