Bending Moment Apparatus
Product Code : EL-AMLE-10615
Quick Answer:
The Bending Moment Apparatus is a structural mechanics test setup used to determine the bending moment and shear force at the hinge section of a beam under different loading conditions. It consists of a teak wood beam made of two hinged sections, together with a spring balance and adjustable screw arrangement that lets the operator calculate the bending moment for any load position and determine the shear force at the hinge. The unit includes a 1 metre span beam with supports, a weight set with loading hangers, a spirit level, and a technical manual, and it is used to plot influence line diagrams for bending moment and shear force.
PRINCIPLE OF OPERATION:
The long and short sections of the teak wood beam are connected by a hinge, and a spring balance with an adjusting screw, mounted at a fixed distance, enables the bending moment to be calculated for any load position. Another special attachment with an adjustable screw is also provided; together with a spring balance and its adjustable screw, this is used to determine the shear force at the hinge section.
