Question 1

Two forces of 30 N and 40 N act concurrently on a point at right angles to each other. What is the magnitude of the resultant force?

50 N 10 N 70 N 1200 N

Correct Answer:

50 N

Question 2

Which set of equations defines static equilibrium for a rigid body subjected to a coplanar (2D) force system?

sum(Fx) = sum(Fy), sum(M) = 0 sum(Fx) = 0, sum(Fy) = 0, sum(M) = 0 sum(Fx) = 0, sum(Fy) = 0, sum(M) = F * d sum(Fx) + sum(Fy) + sum(M) = 0

Correct Answer:

sum(Fx) = 0, sum(Fy) = 0, sum(M) = 0
