Statement: 1
If three forces F1, F2 and F3 are represented by three sides of a triangle and F1 + F2 = −F3, then these three forces are concurrent forces and satisfy the condition for equilibrium.
Statements: II
A triangle made up of three forces F1, F2 and F3 as its sides takes in the same

Question

Statement: 1
If three forces F1, F2 and F3 are represented by three sides of a triangle and F1 + F2 = −F3, then these three forces are concurrent forces and satisfy the condition for equilibrium.
Statements: II
A triangle made up of three forces F1, F2 and F3 as its sides takes in the same order, satisfy the condition for translatory equilibrium.
In the light of the above statements, choose the most appropriate answer from the options given below.
(1) Statement - I is false but Statement - II is true
(2) Statement - I is false but Statement - II is false
(3) Both Statement - I and Statement - II are false
(4) Statement - I and Statement - II are true

Accepted Answer

Statement - I is false but Statement - II is true. Three forces represented by the sides of a triangle taken in order add to zero, giving translatory equilibrium, so Statement-II is true. But such forces act along different lines and are not concurrent, so Statement-I is false. Hence Statement-I is false but Statement-II is true.
