Question

Determine the value of the force exerted by the surface (normal force) on a

8kg block. If the force F = 50 N in the following figure, (Draw the D.C.L.)
Neglect friction.

Answer 1

53.5 N

Step-by-step explanation:

Vertical component of the F force 50 sin30 = 25 N upward

force of gravity = m g = 8 * 9.81 =78.5 N Downward

NET downward force by block on table = net upward force exerted by table = 78.5 -25 =53.5 N
