**This question is confusing me, trying to find an equation for "tensile force" has left me confused since ive found no equation for it just for tension, tensile stress and tensile strain, just wanting to make sure ive not missed anything or done it incorrectly**

1. Homework Statement

1. Homework Statement

At a building site, an iron girder of mass 420 kg is suspended from a crane

by a steel cable. Assume that the cable has a circular cross-section of

diameter 25 mm.

Determine the tensile force in newtons on the cable in kN to 2 decimal

places. (Take the acceleration due to gravity as 9.8 m s−2 and ignore the

mass of the cable).

## Homework Equations

i calculated it as tension assuming tensile force means tension[/B]

T = mg x ma

## The Attempt at a Solution

(420kg x 9.8ms

^{2}) x (420kg x 9.8ms

^{2}) = 8232 kg ms

^{2}

which i then converted to newtons = 8232N (8.23Kn)
