Question

Test #1 Problem #4, Statics, Spring 2021 Bars AB and BCD are an assembly connected with a frictionless pin at point B, and the assembly is supported by frictionless pins at A and C. The assembly is loaded with a 30-lb force at D. Bar AB is a two-force member because the only forces acting on AB are at the pins at A and B. Determine the reaction forces at pins A and C. The solution to this problem must include a free-body diagram of the plate and a sketch of the coordinate system. Do not use a force triangle to apply $\sum F = 0$, use the components of the forces with $\sum F_x = 0$ and $\sum F_y = 0$.

          Test #1 Problem #4, Statics, Spring 2021

Bars AB and BCD are an assembly connected with a frictionless pin at point B, and the
assembly is supported by frictionless pins at A and C. The assembly is loaded with a 30-lb
force at D. Bar AB is a two-force member because the only forces acting on AB are at the
pins at A and B. Determine the reaction forces at pins A and C.

The solution to this problem must include a free-body diagram of the plate and a sketch of
the coordinate system. Do not use a force triangle to apply $\sum F = 0$, use the components of
the forces with $\sum F_x = 0$ and $\sum F_y = 0$.

Test #1 Problem #4, Statics, Spring 2021

Bars AB and BCD are an assembly connected with a frictionless pin at point B, and the
assembly is supported by frictionless pins at A and C. The assembly is loaded with a 30-lb
force at D. Bar AB is a two-force member because the only forces acting on AB are at the
pins at A and B. Determine the reaction forces at pins A and C.

The solution to this problem must include a free-body diagram of the plate and a sketch of
the coordinate system. Do not use a force triangle to apply ∑ F = 0, use the components of
the forces with ∑ Fx = 0 and ∑ Fy = 0.

Step 1

First, let's draw a free-body diagram of the assembly. We have bars AB and BCD connected at point B, and the assembly is supported by pins at A and C. The 30-lb force is applied at point D. Show more…
