7 26. The built up shaft consists of a pipe AB and solid rod BC.The pipe has an inner diameter of 20 mm and outer diameter of 28 mm. The rod has a diameter of 12 mm. Determine the average normal stress at points D and E and represent the stress on a volume element located at each of these points. B. 6EN 4 kN 8 kN 6 kN E

a group of clowns form a human tower on each others shoulders. they each have a mass of 64.7 kg, 75.2kg, 77.8kg and 41.4kg the largest clown is on the bottom. his shoes have a total surface are of 0.015 m^2 on theri soles. what is the pressure in n/m^2 exerted by the bottom clown on the floor?

When a certain liquid freezes, it expands about 10.0%. What would be the pressure increase inside an engine block if the liquid in it froze? (The bulk modulus of the liquid when it solidifies is 2.05  109 N/m2.)

The hoist supports the 115-kg engine. A)Determine magnitude of the force the load creates in member FB, which contains the hydraulic cylinder H. B)Determine magnitude of the force the load creates in member BD.
