False

True

Question 5 of 10

Question 6 of 10

6. Which of the following conditions are true to make the calculations easy?
First condition: We use the method of a joint to find the forces acting over the joints in the space trusses.
Second condition: In this, we start from the joint having at least one known force and at the most two unknown forces.

We neglect both the conditions because calculations are possible without following the first and second conditions

First and second conditions are compulsory and can’t be neglected

We neglect the first condition and only see the second condition

We only see the first condition and neglect the second condition
