Behaviour Of Column Struts Apparatus
Apparatus consist of four spring steel columns which are put along a vertical wooden board. These four columns have different end conditions as below:
1. Both ends pinned
2. Both ends fixed
3. One end pinned and other fixed
4. One end fixed and other end free
Apparatus to be supplied should be complete with a supporting stand and a set of weights.
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.EXPERIMENT MANUAL:
1. To verify the Shear force a cross-section of the beam. 2. To verify the bending moment in cross–section of beam with a flexure condition.APPARTUS SPECIFICATION:
1. Dimensions : 158 cm X 45cm X (h)60cm 2. Total Beam Length : 160 cm with flexure 3. Width of Beam : 5 cm 4. Distance of Length in between : 5 cm 5. Height of beam : 36 mm 6.

Curved Member Apparatus
Apparatus consists of a steel bar which is used to make the different curved members Viz. circle, semicircle with straight arm, a quadrant of a circle and quadrant of a circle with straight arm. The bottom ends of the members are fixed to the base. Under the application of load at free end, its horizontal and vertical deflection can be measured with the help of dial gauges. A dial gauge with 25mm travel (with a magnetic base) is supplied with the apparatus. Apparatus to be supplied should be complete with a supporting stand and a set of weights.
Experimental Capabilities: Apparatus is supplied complete with a supporting stand and a set of weights.
Deflection Of Truss Apparatus
Apparatus consist of 4 panels of a PRATT steel truss, each panel being 40cm in horizontal direction and 30cm in vertical direction. Load can be applied on each panel point. All tension members should be provided with detachable springs so as to obtain appreciable deformation of the member. Direction of the diagonal members may be changed. Apparatus can be used to illustrate visually the nature of forces set up in various members of the Truss. Apparatus to be supplied should be complete with a supporting stand and a set of weights.
Experimental Capabilities: Apparatus is supplied complete with a supporting stand and a set of weights.
Elastic Properties Of Deflected Beam Apparatus
Apparatus consists of a mild steel beam 2.5cm x 3mm in cross section and 100cm long, pinned to two supports 70cm apart situated symmetrically. One of the ends can be fixed or given a known slope by applying a known moment at the end with the help of suspended loads. At the other end also a known moment can be applied. Vertical loads can be applied at various points along the span of the beam. A dial gauge with 25mm travel (with a magnetic base) may be supplied with the apparatus. Apparatus to be supplied should be complete with a supporting stand and a set of weights
Elastically Coupled Beam Apparatus
Apparatus consists of a three parallel bar suspension system with elastic beam at their upper and lower ends. The upper ends of the two outer suspension rods are tied to a vertical wooden board while central suspension rod may be tied to the centre of another elastic beam supported at two outer ends only. Mild steel Apparatus to be supplied should be complete with a supporting stand and a set of weights.
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.
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. At the roller end a chord is attached which is connected further to spring balance. The spring balance records the horizontal reaction, for the measurement of slope and deflection. Both the columns of the portal frame can be clamped (fixed) or pivoted (hinged) and required.EXPERIMENT:
• To study the behavior of a portal frame under different end conditions.TECHNICAL SPECIFICATION:
• Apparatus made up of M.S. plate of rectangular section of 3mm thick x 40cm wide. • Frame is provided with a provision to achieve different end conditions viz. hinged, roller & fixed. • The size of portal will be 40cm x 60cm. Portal may also have a provision for pulley arrangement and hook arrangement for horizontal loading at different positions. • Apparatus is to be supplied complete with a supporting stand and a set of weights • Electronic load cells, displacement cell and Electronic Control Unit (ECU) provided with apparatus. • Software for digital calculations to easily performs by students.OPTIONAL ACCESSORIES:
• PC/Laptop Set.
Redundant Joint Apparatus
Apparatus consists of three suspension members (spring balances) of different stiffness, which are jointed at a point to form the redundant joint. The upper end of the suspension members being tied in a position to a vertical wooden board. Arrangement is provided to apply a vertical load at the joint and to measure its horizontal and vertical displacement on a paper and also elongations and forces in the suspension members by the help of dial gauges. Dial gauges with magnetic base are provided with the apparatus.
