Physics please....?

Question

im confused coz theres no given measurement or anything, its ok if you dont give the exact answer, just tell me how to do it .... or even just how to get the weight..

your mother hung a picture frame against the wall. the picture frame is supported by two wires attached to its two upper corners. If the two wires make the same angle with the vertical, what must be the this angle for each tension in the wires to be equal to the weight of the picture frame.

thanks and have a great day! :)

Answer 1

lol

i would probly remeber if i saw a diagram,

Physics is shite.

Happy today.

Answer 2

You don't have to get the actual weight coz the solution applies for all.

I hope I can draw a figure here but I cant so just bear with my explanation.

if the cords makes an angle x with the vertical and that these cords have a tension equal to the Weight W, then

Weight of Frame = 2 * Vertical component of Tension in each cord (summation of forces along the vertical axis)

W = 2* W*cosx   where Wcosx = component of frame weight along the vertical direction

0.5 = cos x

x = 30 deg from the vertical

Answer 3

anything between zero and 90 degrees - depending on teh elasticity of the material of the wire

For zero degrees it would require infinite elasticity

For 90 degrees it would require zero elasticity - yes - at infinity the two angles would converge to 90
