A bag of cement of weight 370 N hangs from three wires

Two of the wires make angles è1 = 58.6° and è2 = 23.8° with the horizontal. If the system is in equilibrium, calculate the tension T1.

  • physics - ,

    You know the sum of forces is zero, in the vertical and horizontal.

    In the horizontal
    0=T1cos58.6 + T2cos23.8
    In the vertical
    370=T1sin58.6 + ....

    From this, you get two equations, two unknowns.
