## Solution to Problem 133 Pressure Vessel

## Solution to Problem 131 Bearing Stress

**Problem 131**

Repeat Problem 130 if the rivet diameter is 22 mm and all other data remain unchanged.

## Solution to Problem 130 Bearing Stress

**Problem 130**

Figure P-130 shows a roof truss and the detail of the riveted connection at joint *B*. Using allowable stresses of τ = 70 MPa and σ_{b}= 140 MPa, how many 19-mm-diameter rivets are required to fasten member *BC* to the gusset plate? Member *BE*? What is the largest average tensile or compressive stress in *BC* and *BE*?

## Solution to Problem 108 Normal Stress

**Problem 108**

An aluminum rod is rigidly attached between a steel rod and a bronze rod as shown in Fig. P-108. Axial loads are applied at the positions indicated. Find the maximum value of P that will not exceed a stress in steel of 140 MPa, in aluminum of 90 MPa, or in bronze of 100 MPa.

## 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.

## Solution to Problem 105 | Normal Stress

**Problem 105**

A homogeneous 800 kg bar AB is supported at either end by a cable as shown in Fig. P-105. Calculate the smallest area of each cable if the stress is not to exceed 90 MPa in bronze and 120 MPa in steel.
