Kinematics Question 435

Question: P, Q and R are three coplanar forces acting at a point and are in equilibrium. Given P=1.9318kgwt, sinθ1=0.9659, the value of R it’s (in kg wt)

Options:

A) 0.9659

B) 2

C) 1

D) 12

Show Answer

Answer:

Correct Answer: C

Solution:

[c] Psinθ1=Qsinθ2=Rsin150o

1.93sinθ1=Rsin150o

R=1.93×sin150osinθ1=1.93×0.50.9659=1
