Questions
Three concurrent forces of the same magnitude are in equilibrium. What is the angle between the forces? Also name the triangle formed by the forces as sides.
a
600, equililateral triangle
b
1200, equilateral triangle
c
300, an isosceles triangle
d
1200, an obtuse angled triangle
detailed solution
Correct option is B
If the resultant of three concurrent coplaner forces is zero , then the force vectors must form a closed triangle and the sides represent the forces in the same order . If the forces are of equal magnitude then the triangle must be an equilateral triangle .So the angle between any two forces is 1200.Talk to our academic expert!
