2153-PHYS191-01 oursesM My Grades Support Amanda Pizzolato Object on a set of strings, due Sun Feb 8 Thursday, February 5, 2015 01 Topic 4 red 1.00 cable weight Weight W A 49.4 lbf weight is suspended trom a horizontal strut of negligible weight. The force exerted on the strut by the wall is horizontal The angle between the strut and the diagonal cable supporting the strut is 6-59.30 Find the tension Tcable in the diagonal cable supporting the strut In this and all other problems the answers should be calculated in metric (SI) units, and included wiff the answer Answer

Explanation / Answer

First of all convert lbf into Newtons

Therefore 49.4 lbf= 219.742068 N

Now break tension in the cable to its components , its vertical component will Be Tsin(angle=59.3) and horizontal component T cos (angle= 59.3).

Now Putting vertical component equal to weight as their is no other vertical forces therefore

T Sin59.3= 219.742068

Tcable = 255.557 N
