A steel cable with a radius of 1.5 cm support a chairlift at ski area. If the maximum stress is not to exeed `10^(8)` N `"m"^(-2)` , what is the maximum load the cable can support?

Text Solution

Verified by Experts

The braking stress is `10^(8)" Nm"^(-2)`.
`:.` Breaking load
= breaking stress `xx` cross - sectional area
`=10^(8)xx3.14xx((1.5)/(100))^(2)`
`=7.065xx10^(4)N`
