figure
1 of 1
part b
determine the shear force at point c.
express your answer to three significant figures and include the appropriate units.
part c

Explanation:

Step1: Analyze the shear - force concept

The shear force at a point in a beam is related to the external forces acting on the beam. In this case, we consider the horizontal force \(P\).

Step2: Determine the shear force

Since there is no vertical force component (assuming the force \(P = 12\space kN\) is horizontal and the beam is in a state where we are looking for the shear force in the plane of the problem's context, and if we consider the sign convention for shear force. If we assume the right - hand rule for shear force (positive when it causes a clockwise rotation of a small element), and considering the force \(P\) acting on the beam. The shear force \(V_{C}\) is equal to the horizontal force \(P\) (because there are no other forces to balance it in the relevant direction for shear force calculation in this simple case). So \(V_{C}=12\space kN\)

Answer:

\(V_{C} = 12\space kN\)
