Bending Moment & Shear Force Apparatus
INTRODUCTION:
Shear Forces occurs when two parallel forces act out of alignment with each other. For example, in a large boiler made from sections of sheet metal plate riveted together, there is an equal and opposite force exerted on the rivets, owing to the expansion and contraction of the plates.
Bending Moments are rotational forces within the beam that cause bending. At any point within a beam, the Bending Moment is the sum of: each external force multiplied by the distance that is perpendicular to the direction of the force.

1. To verify the Shear force a cross-section of the beam.

Portal Frame Apparatus
DESCRIPTION:
Portal Frames used for the measurement of horizontal reaction are made stiffer by using M. S. flats rectangular cross section (10mm thick and 40mm wide). All are true to shape. The ends can be other fixed of hinged as desired. The end at which horizontal reaction, is to be measured, is provided with ball bearing rollers, which easily rolls on a smooth rolling platform.

Pinned Joint Model
SPECIFICATION:
Model consists of hinged. Model will be able to demonstrate the qualitative behavior of the truss under load. As are very flexible, a compression members will easily it`s bucking i.e. It will curve of plain. The tension member however remains straight and tight. The student will therefore have a visual picture of the type of stresses i.e. Compressive or tensile that member of truss will carry under various positive of the load. In case of pinned joint truss, the student will be able to observe that angle between members at each joint undergo a small change.
