A 74 N weight is suspended by two ropes that make angles of 55° and 75° with the ceiling. Determine the tension in each rope

Respuesta :

Multiply 74 and 55 then divide by 75

Answer:

Step-by-step explanation:

See image

  Vertical forces    -74 + t1 sin 75 + t2 sin 55 = 0

   Horizontal    t1 cos 75 = t2 cos 55

                         t1 = t2 cos 55 / cos 75   = 2.21613 t2

                           ( sub this in the first equation to solve for t2)

     -74 + 2.21613 t2 sin 75 + t2 sin 55 = 0

                 t2 = 25.00 N

        then t1 = 55.41 N
