Trusses are commonly used to span distances between two walls. There are many truss designs, but one of the most common a Howe truss due to its simplicity and efficiency. Trusses usually need to carry both roof loads and ceiling loads. Both types of loads are modeled can be modeled as point loads at the truss joints.
What is known:
 The width of the truss is 10 ft.
 The roof incline angle, θ, is 40°.
 There are loads at each joint as shown in the diagram at the left
 Loads are shown in the diagram.
