ME 202 - Tutorial 6 – Curved Beams For all the problems below, the elastic modulus is E, and the second moment of area is I. Q1. The C-clamp of figure 1 is manufactured using steel with a tensile yield stress 𝜎" = 380 MPa. The frame has the T-section shown. Find the maximum clamping force P, if there is to be a factor of safety of 2.5 against yielding at the point A. Q2. Figure 2 shows a circular ring of mean diameter 350 mm and circular cross section of diameter 100 mm, loaded by equal and opposite 50 kN forces. Find the maximum stress in the ring. For this statically indeterminate problem use Castigliano’s second theorem.
