What is the tension in cord a in this diagram? it would if you answered in newtons but not absolutely necessary. i know the answer already (683 n) i would just like to see how to get to the answer

683 N

Explanation:

If the block is in equilibrium, then the net force acting on it is zero.

We have therefore to resolve each force along the x- and y- direction, and equate the net force along each direction to zero. Doing so, we obtain the following equations:

where

is the tension in cord A

is the tension in cord B

W = 250 N is the weight of the block

From the first equation we get:

And substituting into the second equation, we find the tension in cord A:

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered
