Question

Q5. As shown in the diagram, a bracket is mounted to a rigid structure using four bolts that are
arranged in a square with center to center distance of 22mm. A load whose x.y,z components
as shown in the diagram is applied. Take mass "m" as 180kg
• Find out the tensile and shear loads acting on the bolts
• Size the bolts such that the bolts are reusable (pretension at 75% of proof load). Use
Metric 8,8 grade bolts for this purpose. Use metric standard charts published online for
and mention your source. A factor of safety of 2 should be there in both tension and
shear. Assume the same size bolts are used.
• Support your solutions with relevant free body diagrams.
Note: If you feel any information is not available, take reasonable assumptions and mention the
same

Answer 1

Answer:

Find out the tensile and shear loads acting on the bolts

Size the bolts such that the bolts are reusable (pretension at 75% of proof load). Use Metric 8.8 grade bolts for this purpose. Use metric standard charts published online for and mention your source. A factor of safety of 2 should be there in both tension and shear. Assume the same size bolts are used.
