SIMPLE STRESS

SOLVED PROBLEM AND SOLUTION CHAPTERE-01

PROBLEM: 110

A 12-inches square steel bearing plate lies between an 8-inches diameter wooden post and a concrete footing as shown in Fig. P-110. Determine the maximum value of the load P if the stress in wood is limited to 1800 psi and that in concrete to 650 psi.

SOLUTION: 

    For Wood, 

PROBLEM: 111

For the truss shown in Fig. P-111, calculate the stresses in members CE, DE, and DF. The cross-sectional area of each member is 1.8 in2. Indicate tension (T) or compression (C).

SOLUTION: 

PROBLEM: 112

Determine the cross-sectional areas of members AG, BC, and CE for the truss shown in Fig. P-112. The stresses are not to exceed 20 ksi in tension and 14 ksi in compression. A reduced stress in compression is specified to reduce the danger of buckling.

SOLUTION:

PROBLEM: 113

Find the stresses in members BC, BD, AND CF for the truss shown in Fig. P- 113. Indicate the tension or compression. The cross sectional area of each member is 1600 mm2 .
