Combined Loading

Any functioning component, such as machine parts, structural members, pressure vessels, and so on, are all under the influence of more than one force. When anybody is under the influence of more than one force such as shear forces, bending moments, axial forces, torsion, and so on, then such body is said to be under combined loading. A very practical example of combined loading is the crankshaft of an internal combustion engine (IC engine). The crankshaft of the IC engine is under high rpm, which is caused due to the torsional forces. Due to the presence of piston, counterbalances, and internal imbalances, the crankshaft experiences lateral forces and due to the rise in temperature, the crankshaft undergoes thermal expansion, which pulls the crankshaft along the axial direction and lateral direction. The presence of unbalanced loads along the periphery of the crankshaft also induces a bending moment.

Question

This diagram depicts a T-shaped structural component, showing various dimensions that define its geometry.

- The top horizontal section of the "T" is 20 inches wide and 6 inches tall.
- The vertical part of the "T" that connects the top and bottom sections is 12 inches tall and 2 inches wide.
- At the bottom of the "T," the horizontal section measures 9 inches in width and 6 inches in height.

This T-beam shape is commonly used in construction and structural engineering to provide support where a large load-bearing capacity is needed. The measurements detailed in the diagram help in determining the beam's capacity to bear loads and its application in different structural scenarios.

**Problem 2: Bending Stress Analysis**

A moment of -150 kip-ft (negative 150 kip-feet) is acting at the centroid of the cross section shown.

**Objective**: Determine the bending stress in psi at specific points on the cross section.

**Points of Interest**:
(a) At the top surface of the cross section.
(b) 3 inches down from the top surface of the cross section.
(c) 12 inches up from the bottom surface of the cross section.
(d) 3 inches up from the bottom surface of the cross section.
(e) At the bottom surface of the cross section.

**Diagram Overview**:
The accompanying diagram illustrates a beam with an I-shaped cross section. A negative moment $ M $ is acting at the centroid. Arrows are pointing towards the left, indicating the direction of the forces associated with the moment.

**Concepts Utilized**: Bending stress calculations use the formula $\sigma = \frac{M \cdot c}{I}$, where:
- $ \sigma $ is the bending stress,
- $ M $ is the moment,
- $ c $ is the distance from the neutral axis to the point of interest,
- $ I $ is the moment of inertia of the cross section.

This setup is a typical problem to evaluate the distribution of stresses within beam structures, critical in structural engineering and materials science.
