Q3. The аssembly cоnsists оf twо sections of gаlvаnized steel pipe connected together using a reducing coupling at B. The smaller pipe is 10-in. long and has an outer diameter of 75 in. and an inner diameter of 0.68 in., whereas the larger pipe is 15-in. long and has an outer diameter of 1 in. and an inner diameter of 0.86 in. If the pipe is tightly secured to the wall at C, Determine the maximum shear stress in each section of the pipe when the couple is applied to the handles of the wrench. What is the angle subtended by the handles of the wrench with respect to the unloaded initial position? Formula Reference Sheet.pdf
