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
Two Hinged Arch Apparatus
DESCRIPTION:
The two hinged arch is a statically indeterminate structure of the first degree. The horizontal thrust is the redundant reaction and is obtained y the use of strain energy methods. Two hinged arch is made determinate by treating it as a simply supported curved beam and horizontal thrust as a redundant reaction.EXPERIMENT:
• To study experimentally a two hinged arch for the horizontal displacement of the roller end for a given system of loading and to compare the same with those obtained analytically. • To obtain the influence line ordinates for horizontal thrust experimentally in a two hinged arch by moving a load along the span and to compare the same with those obtained theoretically.TECHNICAL SPECIFICATION:
• Apparatus has a span of 100cm and rise 25cm. • Both ends should have hinge but one of the ends should also be free to move longitudinally. • A lever arrangement fitted at this end for the application of known horizontal inward force for measuring the horizontal thrust. Along the horizontal span of the arch various points are marked at equidistant for the application of load. • This being a statically indeterminate structure of the first degree. • A dial gauge with 25mm travel (with magnetic base) is to be supplied with the apparatus. • Mild steel apparatus 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.
Verification Clarke S Maxwell Reciprocal Theorem
Apparatus for Verification of Clarke’s Maxwell Reciprocal Theorem
Apparatus consist of a mild steel beam 100cm long and 1.25cm x 4mm in cross section with graduations at every 10cm along the length. It should be supported on two knife edge supports 70cm apart with a 30cm overhang on one side. Reciprocal theorem can be verified by direct measurements of the deflections of various points with the help of a dial gauge due to a load placed at the reciprocal points. A dial gauge with 25mm travel (with a magnetic base) should be supplied with the apparatus. Apparatus to be supplied should be complete with a supporting stand and a set of weights.
Experimental Capabilities: To verify Clerk’s Maxwell reciprocal theorem by means of a mild steel be
