Design Against Fluctuating Loads

Machine elements are subjected to varieties of loads, some components are subjected to static loads, while some machine components are subjected to fluctuating loads, whose load magnitude tends to fluctuate. The components of a machine, when rotating at …

Design Against Fluctuating Load

Stress is defined as force per unit area. When there is localization of huge stresses in mechanical components, due to irregularities present in components and sudden changes in cross-section is known as stress concentration. For example, groves, keyways…

Textbook Question

Chapter 18, Problem 18.18P

For Problems 18.18 through 18.21, use the Euler-Johnson formulas, Equations (18.9) end (18.10), and a modulus of elasticity of 30,000,000 psi.

18.18 Calculate the allowable axial compressive load for a bar of rectangular cross section that measures 1 in. by 2 in. and is 20 in. long. The member is made of AISI 1040 hot-rolled steel. Use a factor of safety of 3.5 and assume the member is pin-connected.

A uniform Steel strut (material Modulus of Elasticity 200 GN/m2, Poisson’s Ratio 0.3) oflength 0.5m and width 100 mm is restrained as appropriate at one end and under an axialtensile load of 25 KN applied to the other end face. It has been initially designed with a thickness of 5mm. This gives a hand calculated stressvalue of 50 MN/ m2, which is a quarter of the material’s Yield Stress, of 200 MN/m2, givinga factor of safety of four. Conduct computer FEA simulations applying element types(tetrahedral, hexahedral) and a range of element sizes (2mm, 5mm & 10mm), presenting findings in a tabulated format.

Calculate the critical load of a steel circular column for pinned-pinned boundary conditions using Johnson formula. The length of column is 300 mm, diameter is 60 mm and slenderness ratio is 40. The modulus of elasticity of steel is 207 GPa and yield strength is 300 MPa. Use safety factor 2.5. Select one: O a. 756.6 kN b. 715.3 kN c. 798.4 kN
