Suspension Bridge Apparatus

DESCRIPTION:

Cables are frequently used to support loads over large spans such as cable stayed for suspension bridges, cable car systems and stadium roof. They are used extensively for permanent guys on structures such as microwave towers and derricks. They are also used for temporary guys during erection. The only force in a cable is direct tension. They are too flexible to carry any moment. A cable is used to carry concentrated loads, uniformly distributed load along its length and uniformly distributed load along the horizontal span. It takes the shape of a polygon under concentrated loads, a catenary under uniform load along its length (such as its own weight), and a parabola under uniform load along the horizontal span.

EXPERIMENT:

• Study the Extension of each spring Balance Left & Right Both. • Study of the effect of a point load

TECHNICAL SPECIFICATION:

• Apparatus Consists of two mild steel cables 0.5cm diameter in cross section and 150cm long, pinned to two supports 90cm apart situated symmetrically. • One of the ends can be converted to a roller by applying a known load at the end with the help of suspended pulley system. • Vertical loads can be applied at various points along the span of the beam. • A dial gauge with 25mm travel (with a magnetic base) is to be supplied with the apparatus complete with a supporting stand and a set of weights.

Open Wind Tunnel Apparatus

Technical Description

A wind tunnel is the classic experiment system for aerodynamic flow experiments. The model being studied remains at rest while the flow medium is set in motion, and thus the desired flow around the model is generated. Open wind tunnel used to demonstrate and measure the aerodynamic properties of various models. For this purpose, air is drawn in from the environment and accelerated. The air flows around a model, such as an aerofoil, in a measuring section. The air is then decelerated in a diffuser and pumped back into the open by a fan. The carefully designed nozzle contour and a flow straightener ensure a uniform velocity distribution with little turbulence in the closed measuring section. The flow cross section of the measuring section is square. The built-in axial fan with guide vane and a variable-speed drive is characterised by an energy-efficient operation at high efficiency. Air velocities of up to 28m/s can be reached in this open wind tunnel. The trainer is equipped with an electronic two-component force sensor.Lift and drag are detected and displayed digitally. The air velocity in the measuring section is displayed on the inclined tube manometer. The tube manometers is recommended for measuring the pressure curves in drag bodies. Extensive accessories allow a variety of experiments, for example lift measurements, pressure distributions, boundary layer analysis or visualisation of streamlines. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.

Learning Objectives & Experiments

– Determine drag and lift coefficients for different models – Pressure distribution when flowing around drag bodies – Boundary layer analysis – Investigation of flutter – Wake measurement

Features

* Open wind tunnel for a variety of aerodynamic experiments * Homogeneous flow through the flow straightener and special nozzle contour * Transparent measuring section

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.
