Question

A push of 180 N and pull of 350 N act simultaneously at a point. Find the resultant of the
forces, if the angle between them be 135º.
[Ans. 494 N: 30°]​

Answer 1

Answer:

Resultant Force = 256.52 N atan Angle of 27.2 degree w.r.t. force 350 N

Explanation:

Let P = 180 N, Q = 350 N and Resultant Force = R

R = √{ P ^2 + Q^2 + 2× P ×Q × cos(135)}

=√{180^2 + 350^2 + 2×180×350× cos135}

=256.52 N

$tan \alpha = 180 \div 350 = 0.51 \\ \alpha = 27.2 \: degree \: w.r.t. \: force \: 350N$
