Compute the vertical and horizontal components for the given

Compute the vertical and horizontal components for the given values of P and theta. The angle is measured clockwise from the positive X axis to the force P, as shown. 320Ib, 20 degree 640 Ib, 30 degree 320 Ib, 40 degree 320 Ib, 88 degree

Solution

vertical component = -P sin theta

horizontal compoenent = P cos theta

a)

horziontal = 320 cos 20

vertical = -320 sin20

b)

horziontal = 640 cos 30

vertical = -640 sin30

c)

horziontal = 320 cos 40

vertical = -320 sin40

d)

horziontal = 320 cos 88

vertical = -320 sin 88
