Torsion Of Rods Apparatus
INTRODUCTION:
A torsion test is quite instrumental in determining the value of modulus of rigidity of a metallic specimen. The value of modulus of rigidity can be found out thought observations made during the experiment by using the torsion equation.
APPARATUS:
1. A torsion testing machine.
2. Twist meter for measuring angles of twist
3. A steel rule and Vernier Caliper or micrometer

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.
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.
Three Hinged Arch Apparatus
The mild steel model has a span of 100cm and rise 25cm, with hinges at supports and crown. One of the ends should rests on rollers. Along the horizontal span of the arch various points are marked at equidistant for the application of load. This being a statically determinate structure, the horizontal thrust developed under the action of any load system can be theoretically calculated and will also be measured directly by neutralizing the outward movement of the roller end. A dial gauge with 25mm travel (with magnetic base) may be supplied with the apparatus. Apparatus to be supplied should be complete with a supporting stand and a set of weights.
Unsymmetrical Bending Apparatus
DESCRIPTION:
Apparatus consist of an angle of size 1” x 1” x 1/8” or in equivalent metric units of length 80cm is tied as a cantilever beam. The beam is fixed at one end such that the rotation of 450 intervals can be given and clamped such that the principal axis of its cross-section may be inclined at any angle with the horizontal and vertical planes. Also arrangement is provided to apply vertical load at the free end of the cantilever and to measure horizontal and vertical deflection of the free end. A dial gauge with magnetic base is supplied with the apparatus.EXPERIMENT MANUAL:
• To study the behavior of a cantilever beam under symmetrical and unsymmetrical bending. • Using a Dial gauge shown a increasing and decreasing of heights.
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.
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
Shear Centre Apparatus
Apparatus consists of sturdy base frame and Channel, Equal angle, Semicircle and Z-Section are supplied with apparatus. Standard length of each of the four sections in M. S. is supplied. Each is provided with end clamp for fixing to the rigid bracket. A special load hanger is provided so as to change the load position so that with the help of two dial-gauges, the vertical plane of Shear-centre for the particular section can be determined.
