Question

An object is on a horizontal surface. three forces act horizontally on the object: 3 N to the left, 12 N to the right, 1 N to the left. At the same time, another three forces act vertically on the object: 4 N upwards, 10 N downwards , 2 N upwards.

determine the resultant horizontal and vertical forces acting on the object.

​

Answer 1

Resultant horizontal force : 16 N

Resultant vertical force : 4 N

Explanation: Force acting on left : 3N

Force acting on left : 1 N

Forces acting on left : 3N + 1N = 4N

Force acting on right : 12 N

Resultant horizontal force : 12 N - 4 N = 16 N

Force acting upwards : 4 N

Force acting upwards : 2 N

Forces acting upwards : 4 N + 2 N = 6 N

Force acting downwards : 10 N

Resultant vertical force : 10 N - 6N = 4 N
