The truss which follows the law $n =$ _________ is known as simple truss
The truss which follows the law $n =$ _________ is known as simple truss
Show Hint
Remember that the minimum stable plane truss is a triangle with $3$ members and $3$ joints.
Plugging $j = 3$ into the equation $n = 2j - 3$ gives $n = 2(3) - 3 = 3$, verifying the formula immediately.
Plugging $j = 3$ into the equation $n = 2j - 3$ gives $n = 2(3) - 3 = 3$, verifying the formula immediately.

- $n = 2j + 3$
- $n = 2j - 3$
- $n = 3j + 2$
- $n = 3j - 2$
