The hook made from steel of diameter d is loaded as shown Fo

The hook, made from steel of diameter d, is loaded as shown. For d = 0.6 in and P = 1200 lb, the maximum normal stress at the built-in section is best given by 38.2 ksi 4.24 ksi 21.2 ksi 76.4 ksi

Solution

sol:

given d = 0.6 in and P = 1200 lb

maximum normal stress = P/area

area =(pi*d²)/4

= (3.14*(0.6)²)/4

=4244.13

= 4.24 ksi
