Homework Statement
If the 4.4-kg block is suspended from the pulley B and the sag of the cord is d = 0.15 m, determine the force in cord ABC. Neglect the size of the pulley. (Figure 1)
Express your answer to three significant figures and include the appropriate units.
Homework Equations
The Attempt at a Solution
r(BC) = (x^2 + .15^2)^.5
r(AB) = [(.4-x)^2 + (.15^2)]
T(x) = r(BC)cos(theta) - r(AB)cos(theta)
T(y) = r(BC)sin(theta) + r(AB)sin(theta) - 43.164
I tried adding r(BC) + r(AB) and then grphing to find the zeros but that was wrong.
I also have; x/cos(theta) + .4-x/cos(theta) = .4cos(theta)
not sure how to proceed.
