A central horizontal section of a hook is an I-section with inner width = 45mm, middlewidth=15mm, outer width =30mm and inner thickness =22.5mm, middle thickness=30mm and outer thickness =15mm (i.e.,b = 45mm, b2 = 15mm, b3 = 30mm,t, =225mm, t2 = 30mm and t3 = 15mm). The load line passes through the centre of curvatureand is at a distance of 30mm from the inside edge of the section. The hook carries aload P. Determine the magnitude of P if the maximum stress in the hook is not to exceed120N/mm2. What will be the maximum compressive stress in the hook for that value ofthe load.

225mm, t2 = 30mm and t3 = 15mm). The load line passes through the centre of curvature
and is at a distance of 30mm from the inside edge of the section. The hook carries a
load P. Determine the magnitude of P if the maximum stress in the hook is not to exceed
120N/mm2. What will be the maximum compressive stress in the hook for that value of
the load.
