1. Two cables are pulling on a steel beam. Both attached at the same location (0, 0). the first cable pulls with a force of 1 500 newtons at a 76° angle and the second cable pulls with a force of 2100 newtons at a 138° angle.

(a) Sketch two vectors that model this situation. Draw to scale!

(b) Express each vector in component form, as (a1 , a2)

(c) Find the sum of the two vectors, which will be the

Resultant force on the steel beam

(d) Find the magnitude and direction angle of the resultant force.

(c) Use the parallelogram rule to sketch the resultant force.
