As the angle between two concurrent forces is
decreased from 55° to 15°, the magnitude of
the resultant force

Respuesta :

Answer:

resultant increases by factor of 1.12

Explanation:

EDITED :

Assume force = 1  for simplicity and one vector is on the x axis

at 55 degrees

   horizontal components = 1 + cos 55 = 1.574

   vertical component = sin 55 = .8192

         resultant = 1.77

at 15 degrees

    horizontal components = 1 + cos 15 = 1.966

    vertical component  = sin 15 = .2588

         resultant = 1.98

resultant increases by  1.98 / 1.77 = 1.12 original
