Final answer:
The method of joints and the method of sections can be used to determine the force in each member of a truss. These methods involve analyzing the forces at each joint or cutting the truss into sections. Equilibrium equations can be used to solve for unknown forces.
Step-by-step explanation:
The method of joints can be used to determine the force in each member of the truss. It involves analyzing the forces at each joint in the truss to find the unknown forces. The method of sections can also be used to determine the force in each member. It involves cutting the truss into sections and analyzing the forces in each section.
Once the forces in each member are determined, you can use the equilibrium equations to solve for the unknown forces. For example, you can use the sum of the forces in the x-direction and the sum of the forces in the y-direction to find the forces in each member.
