Example 6 A hollow cylinder 2 m long has an outside diameter of 50 mm and inside diameter of 30 mm. If the cylinder is carrying a load of 25 kN, find the stress in the cylinder Also find the deformation of the cylinder, if the value of modulus of elasticity for the cylinder material is 100 GPa.

A scuba tank is being designed for an internal pressure of 2,685 psi with a factor of safety of 2.0 with respect to yielding. The yield stress of the steel is 66,000 psi in tension and 30,000 psi in shear. (Assume that the given radius or diameter is an inside dimension and that all internal pressures are gage pressures.) (a) If the diameter of the tank is 7.0 in., what is the minimum required wall thickness (in inches)? inches (b) If the wall thickness is 0.25 in., what is the maximum acceptable internal pressure (in psi)? psi

4. Why is modulus a characteristic property but not yield strength.

hi, can you help me with all parts of this question. thank you

(Solid Mechanics) Explain how to construct the upper right corner (red boundary indicated below) of the envelope for the maximum shear stress criterion.

Solve it

If Young's modulus of some material is 150 GPa and shear modulus is 50 GPa, find the poisson's ratio of that material.

need correct ans

Q3: Two material were tested in tension, the first is aluminum alloy has stress-strain curve define by 300 MPa was fracture after 35% reduction in area. The other a copper alloy has stress-strain curve define by=100+120 MPa was fracture after 98% elongation. Which alloy have more toughness? Support your answer with the sketch.?
