Question

A block having a mass of m=15 is suspended via two cables. The angles are as follows: a=19-degree, and b=26-degrees.

a) write an expression for the sum of the forces in the x direction in terms of T1, T2, m, g, angle a and b. Use the specified coordinate system.
b) write an expression for the sum of forces in the y direction in terms of T1, T2, m, g, angles a and b. use the specific coordinate system.
c) solve for the numeric value of T1, in newtons.
d) solve for the numeric value of T2, in newtons.

Answer 1

a) Fx = T1cos(a) + T2cos(b)
b) Fy = T1sin(a) + T2sin(b) - mg
c) T1 = (mg - T2sin(b))/cos(a)
d) T2 = (mg - T1sin(a))/sin(b)
