Problem no.8<br />
The frame punch press is shown in fig. 1.7s. Find the stress in inner and<br />
outer surface at section A-B the frame if F = 5000N<br />
Solution:<br />
Draw the critical section as shown in the<br />
figure.<br />
Inner radius of curved beam ri = 25mm<br />
Outer radius of curved beam ro = 25+40<br />
= 65mm<br />
