(Solved): What is the internal resultant normal force in member \( E F \) in \( N \) ? (tension is positive, ...

What is the internal resultant normal force in member \( E F \) in \( N \) ? (tension is positive, compression is negative) QUESTION 2 What is the internal resultant normal force in member \( B F \) in \( N \) ? (tension is positive, compression is negative) QUESTION 3 The truss below is subject to the loads as shown. All of the members are attached at plates and can be treated as pin connected. The truss is attached to the ground at a pin joint at A and a roller at \( \mathrm{C} \). What is the internal resultant normal force in member \( \mathrm{BC} \) in \( \mathrm{N} \) ? (tension is positive, compression is negative)
