Question

If the two wires make the same angle with the vertical, what must this angle be if the tension in each wire is equal to 0. 75 of the weight of the frame? (neglect any friction between the wall and the picture frame. ).

Answer 1

Answer:

48.24

Explanation:

Given that,

Tension

Let be the angle of wires with vertical

The total force in vertical direction from the wires

We need to calculate the angle

Using balance equation

Put the value of T in the equation

Hence, The angle is 48.24°.
