Asked by Sam

A box weighing 450 N is hanging from two chains attached to an overhead beam at angles of 70 degrees and 78 degrees to the horizontal. Determine the tensions in the chains.

Answers

Answered by Damon
T1 cos 70 - T2 cos 78 = 0 (no horizontal force)
T1 sin 70 + T2 sin 78 = 450 (weight = total force up)
solve 2 equations, two unknowns.
