Question
In figure A, the homogeneous rod of constant cross section is attached to unyielding supports. In figure B, a homogeneous bar with a cross-sectional area of 600 mm2 is attached to rigid supports. The bar carries the axial loads P1 = 20 kN and P2 = 60 kN, as shown.
1. In figure A, derive the expression that calculates the reaction R1 in terms of P, and the given dimensions.
2. In figure B, calculate the reaction (kN) at A.
3. In figure B, calculate the maximum axial stress (MPa) in the rod.
