Question

Consider the 45 N weight held by two cables
shown below. The left-hand cable is horizon-
tal.
a) What is the tension in the cable slanted
at an angle of 50?
Answer in units of N.
007 (part 2 of 2) 10.0 points
b)What is the tension in the horizontal cable?

Answer 1

well, if the right hand is horizontal, the left hand is holding the weight in the vertical

a) 45/tensionright = sin50 if the 50 degrees is measured from the horizontal.
The tension in the left cable has to equal the horizontalcomponent of tension in the slanted cable: tensionleft*cos50
