What is the solution for problem in the pictures I have uploaded

10.12 A strip of steel 3 mm thick and 35 mm wide is bent round a cylindrical drum
4 m in diameter. Determine the maximum stress set up in the strip and the
bending moment which has to be applied to bend the strip to this curvature
(E = 200 GPa).

10.13 A metal pipe with an outside diameter of 75 mm and an inside diameter of
65 mm is simply supported over a span of I metres and subjected to an axial
pull of W kN, Determine the value of l and W given that the top edge of the
pipe must have zero stress at the section where the maximum stress at the
bottom edge is 75 MPa. The density of the pipe material is 7,8 Mg/m2.

10.14 A water channel is made of sheet metal 3 mm thick, It has outside measure-
ments of 400 mm wide and 200 mm deep. Calculate the maximum allowable
depth of water in the channel if it is simply supported over a span of 7 m.
The maximum allowable bending stress is not to exceed 35 MPa. Neglect the
(97 mm
mass of the channel. The density of water is 1 000 kg/m'.
