Bending Moment Apparatus
Bending Moment Apparatus (Product Code: SLE/MCE/23) is a hinged-beam test rig used to measure the shear force and bending moment at a beam section under different loads in strength of materials and structures laboratories. Its 1 m span teak wood beam is made of long and short sections joined by a hinge, and spring balances with adjusting screws measure the internal forces while a spirit level returns the beam to its original position. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Bending Moment Apparatus Used For?
Shear force and bending moment diagrams are central to beam design, yet students rarely see those internal forces measured. Here the beam is divided at a section and bridged by a hinge, so the forces at that section have to be carried by the spring balance arrangements. After hanging loads at chosen positions, students turn the adjusting screw until the spirit level shows the beam back in its original position, read the spring balance and use the fixed lever distance to work out the bending moment; a similar reading at the hinge gives the shear force.
Comparing these measured values with hand calculations from statics confirms the theory for loads at different positions. Moving a single load step by step across the span and plotting the reading at the section builds the influence line diagram, a topic civil and mechanical students often find abstract on paper. With the technical manual guiding each experiment, it is practical engineering lab equipment for colleges and polytechnics in India.
OEM Manufacturer
The Bending Moment Apparatus is manufactured by ScienceLab as the OEM. Jain Scientific Equipments Private Limited, the registered company behind the ScienceLab brand, makes it at its own licensed factory at Saha, Ambala, Haryana, India, and supplies it factory-direct to engineering colleges, polytechnics, dealers and importers.
Ask us about repeat orders, additional loading hangers or spare spring balances; the manufacturer handles these requests itself. The ScienceLab company profile has more details.

Frequently Asked Questions
What experiments can be done with the Bending Moment Apparatus?
The Bending Moment Apparatus is used to determine shear force and bending moment at a beam section for different loading conditions, and to draw influence line diagrams for bending moment and shear force by moving a load across the span.
What is the beam of the Bending Moment Apparatus made of?
The Bending Moment Apparatus uses a teak wood beam with a 1 m span on supports. The beam is made of long and short sections connected by a hinge, which is where the shear force is measured.
How are forces measured on the Bending Moment Apparatus?
The Bending Moment Apparatus measures bending moment with a spring balance and adjusting screw mounted at a fixed distance, and shear force with a spring balance and adjustable screw at the hinge section. A spirit level confirms the beam is restored to its original position.
Which weights are supplied with the Bending Moment Apparatus?
The Bending Moment Apparatus comes with a weight set and loading hangers, but the individual mass values are not stated in the product listing. Ask through our contact page and the quotation will list the weights included.
Does the Bending Moment Apparatus include instructions?
Yes. A technical manual accompanies the Bending Moment Apparatus, so staff can set up each shear force, bending moment and influence line experiment and guide students through the readings and calculations.
Who manufactures the Bending Moment Apparatus?
The Bending Moment Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations for India and international markets come direct from the manufacturer.
