Question

Compute the diameter of a square link subjected to a compres- sive load of 27,000 lbs. Modulus of elasticity 30 x 106 psi. Proportionality limit 38,000 psi, working stress - 7000 psi, length of the link 55 in.

Answer 1

The diameter of a square link is 0.0233 inch.

Step-by-step explanation:

Given that,

Load = 27000 lbs

Modulus of elasticity
`E= 30*10^(6)\ psi`

Working stress
`\sigma=7000\ psi`

length l = 55 in

We need to calculate the diameter of a square link

Using formula of stress

`\sigma=(Force)/(Area)`

`7000=(27000)/(\pi* d* L)`

Put the value into the formula

`d=(27000)/(7000*3.14*55)`

`d=0.0223\ inch`

Hence, The diameter of a square link is 0.0233 inch.
