PROBLEM 1.

Two solid cylindrical rods AB and BC are welded together at B and loaded as shown. Knowing that and find the average normal stress at the midsection of ( a ) rod AB , ( b ) rod BC. SOLUTION ( a ) Rod AB : Force: Area: Normal stress: t ( b ) Rod BC : Force: Area: Normal stress: t

Two solid cylindrical rods AB and BC are welded together at B and loaded as shown. Knowing that the average normal stress must not exceed 150 MPa in either rod, determine the smallest allowable values of the diameters d 1 and d 2. SOLUTION ( a ) Rod AB : Force: Stress: Area:  ( b ) Rod BC : Force: Stress: Area: 

Two solid cylindrical rods AB and BC are welded together at B and loaded as shown. Determine the magnitude of the force P for which the tensile stresses in rods AB and BC are equal. SOLUTION ( a ) Rod AB : ( b ) Rod BC : t

A strain gage located at C on the surface of bone AB indicates that the average normal stress in the bone is 3.80 MPa when the bone is subjected to two 1200-N forces as shown. Assuming the cross section of the bone at C to be annular and knowing that its outer diameter is 25 mm, determine the inner diameter of the bone’s cross section at C. SOLUTION Geometry: 
