Question

Q.31. Determine a unit vector perpendicular to both Ā= 2 +ỹ + and ] = î - ġ + 2Ń
Q.32. What are concurrent forces? Obtain the condition for the equilibrium of three concurrent forces?​

Answer 1

Answer:

2.

Conditions of Static Equilibrium of Concurrent Forces

The sum of all forces in the x-direction or horizontal is zero. The sum of all forces in the y-direction or vertical is zero. Two forces are in equilibrium if they are equal and oppositely directed. Three coplanar forces in equilibrium are concurrent.
