As in Fig. 1-11c, a hole is to be punched out of a plate having a shearing strength of 40 ksi. The compressive stress in the punch is limited to 50 ksi. (a) Compute the maximum thickness of the plate in which a hole 2.5 inches in diameter can be punched. (b) If the plate is 0.25 inch thick, determine the diameter of the smallest hole that can be punched.
The uniform beam is supported by two rods AB and CD that have cross-sectional areas of 10 𝑚𝑚2 and 15 𝑚𝑚2, respectively. Determine the intensity w of the distributed load so that the average normal stress in each rod does not exceed 300 kPa.
Determine the resultant internal normal force, shear force, and bending moment at point C in the beam.
