Question
**Gear/Pulley Mechanism Analysis** In this diagram, a gear/pulley mechanism is displayed in a top view configuration. The system includes several components with specified dimensions and movements: 1. **Initial Gear Drive**: The gear located on the lower left is driven at a speed of 5 degrees per second (deg/s). The radius of this gear is 50 mm. 2. **Gear System**: - The first gear, with a 50 mm radius, engages with a larger gear of 100 mm radius. - This 100 mm radius gear is connected via a belt to a significantly larger gear with a radius of 200 mm. The belt extends 300 mm on both sides from the center. 3. **Pulley and Rod System**: - Attached to this 200 mm gear is a pulley of 75 mm radius. - A rod, connected to a 150 mm pulley, extends 280 mm to a defined tip. - The pulley itself is 150 mm in diameter and connected via belt loops each measuring 300 mm. **Tasks**: (a) Determine the rotational rate of the rod in degrees per second (deg/s). (b) Analyze and state the direction of the rod's rotation: clockwise (CW) or counterclockwise (CCW). (c) Calculate the speed of the rod's tip in millimeters per second (mm/s). The system utilizes mechanical advantage through gear ratios and belt drives to achieve motion transfer and speed modulation across the connected elements.
