Concept explainers

Torsion

In mechanical engineering, torque, torsion, and twisting moment are three of the most important concepts which have different meanings. Torque is the consequence of a moment of a force that produces an angular acceleration in a body or induces rotational kinetic energy in a body. For instance, in an automobile, the power transmission shaft is a body that is always under rotation due to the external torque acting on it, this torque is created by the engine.

Question

**Problem 8-17:**

If the coefficient of static friction between the rear wheels of the tractor and the ground is \( \mu_s = 0.6 \), determine if the rear wheels slip or the front wheels lift off the ground as the engine provides a torque \( M \) to the rear wheels. What is the torque needed to cause the motion? The front wheels are free to roll. The tractor weighs 2500 lb and has a center of gravity at \( G \).

**Diagram Explanation:**

The image shows a tractor with the following labeled elements:

- The center of gravity \( G \) is marked above the rear wheel, indicating the overall balance point of the tractor.
- The tractor is pulling a chain attached to a stump.
- There are measurements indicating distances:
- The distance \( A \) from the front wheels to the center of gravity is labeled as 5 ft.
- The distance \( B \) from the center of gravity to the rear wheels is labeled as 3 ft.
- Another measurement from the rear axle \( O \) to the point where the chain is attached is labeled as 2 ft (both horizontally and vertically).

The image illustrates the scenario described in Problem 8-17, with a person operating the tractor.
