Question

A 13 mm. diameter bar is being pulled by a load of 1000 kg. What is the pressure in psi.

Answer 1

pressure = 10704 Psi

Step-by-step explanation:

given data

diameter = 13 mm = 13 × 0.0394 = 0.5122 inch

load = 1000 kg = 1000 × 2.205 = 2205 pound

we convert these given values to pound and inches so we can solve our answer in Psi units

to find out

pressure

solution

we know pressure formula that is express as

pressure =
`(load)/(area)` ..................1

here area =
`(\pi )/(4) (0.5122)^2`

area = 0.206 in²

so from equation 1 we put value and get pressure

pressure =
`(2205)/(0.206)`

pressure = 10703.88 psi

pressure = 10704 Psi
