## Solution to Problem 125 Bearing Stress

## Normal Stresses

Stress is defined as the strength of a material per unit area or unit strength. It is the force on a member divided by area, which carries the force, formerly express in psi, now in N/mm^{2} or MPa.

where P is the applied normal load in Newton and A is the area in mm^{2}. The maximum stress in tension or compression occurs over a section normal to the load.

## Solution to Problem 114 Normal Stress

**Problem 114**

The homogeneous bar ABCD shown in Fig. P-114 is supported by a cable that runs from A to B around the smooth peg at E, a vertical cable at C, and a smooth inclined surface at D. Determine the mass of the heaviest bar that can be supported if the stress in each cable is limited to 100 MPa. The area of the cable AB is 250 mm^{2} and that of the cable at C is 300 mm^{2}.

## Solution to Problem 107 Normal Stress

**Problem 107**

A rod is composed of an aluminum section rigidly attached between steel and bronze sections, as shown in Fig. P-107. Axial loads are applied at the positions indicated. If P = 3000 lb and the cross sectional area of the rod is 0.5 in^{2}, determine the stress in each section.
