Aluminum Steel Q1

If the axial rigidity of steel bar of 1m length is 200 x 107 N, what will be the axial flexibility of the bar?

Two forces are applied to a flywheel 50 cm in diameter. Each force is 500 N. The shaft is fixed to the wall using three grade 5 steel bolts. The distance between the bolts and the axis of rotation is 10 cm.    (a) What moment of resistance must develop the three bolts together    Answer: 250 Nm    (b) What is the resistance force F of each bolt?   Answer: 833.3 N    (c) What is the diameter of the bolts if their factor of safety is 10?    Answer: 4.14mm

EXAMPLE 3.9 Finite-element²¹ analysis shows that a long structural component car- ries a uniform axial stress of 35 MPa (T) (Figure 3.29). A hole in the center needs to be drilled for passing cables through the structural component. The yield stress of the material is 200 MPa. If failure due to yielding is to be avoided, determine the maximum diameter of the hole that can be drilled using a factor of safety of 1.6. 10 mm H = 100 mm -d- Figure 3.29 Component geometry in Example 3.9.

Pls box ur answer thx u

A fuel transportation industry uses a spherical 1045 carbon steel pressure vessel with a diameter of 800 mm and a thickness of 30 mm, covered with a brittle varnish that cracks in the vessel cover when the deformation exceeds 200 x 106. What is the value of the internal pressure that causes the varnish to develop cracks? (Assume E = 205 GPa and v = 0.30). Explain you answer.

show step by step solution so that i can know the process thank yousubject:mechanic of deformable bodies
