The main part of the apparatus is a precision-engineered rigid aluminium base, with legs and levelling feet. At one end is a loading device which uses a screw to apply loads to the struts. The screw is in fixing blocks with bearings to give precise and easy load application. The Loading and Buckling of Struts allows tests on a full range of struts. They allow students to create any combination of pinned or clamped end conditions for the strut under test. Supplied is a set of special end fittings for tests with various eccentricities to show the effect of eccentric loading. It shows load and deflection characteristics and buckling loads for various strut lengths, Cross-section and end conditions. It also allows studies of the effect of eccentric loading. The equipment includes a lateral pull attachment for Students to apply light biasing loads, or larger side loads, as needed. Students can also set up the apparatus to examine flexural rigidity and general beam deflection theory. An optional set of extra specimens allows extra tests to show students some of the more complicated problems found in strut design. Holders are at both the loading and load measuring ends.
The two special struts show how buckling loads may be lower than the ideal values, because of two reasons:
Imperfect shearing connections between the parts of a compound strut
Flexure of the end fixings.
Lobe pumps are used for delivering highly viscous and highly abrasive media. In a lobe pump two non-contact pistons rotate in two cylindrical chambers. In contrast to rotodynamic pumps, a positive displacement pump moves the medium by means of closed conveying chambers. With each revolution, they deliver the same volume.
Learning Objectives And Experiments:
Power requirement, hydraulic power, pump efficiency
Recording of pump characteristics, system characteristics, operating point.
The active element consists of a non-metallic circular cylinder coated with an electrically conductive surface and circumferential contacts at each end. Under the conducting surface is a thermocouple designed to measure the local temperature. The Local Heat Transfer Element includes a black plastic plate with circular access hole designed to fit the aperture in the Cross Flow Heat Exchanger duct. The active element has a circular graduated flange that fits in the access hole and allows the active element to be rotated about its central axis while in the airstream.
Experimental Capabilities:
Determination of the local heat transfer coefficient at the stagnation point on a cylinder in crossflow
Investigation of polar heat transfer coefficient for a single tube in a transversely flowing airstream at speeds of up to 30m/s.
Induction Hardened and Tempered Jaws.
Jaws made from Selected Carbon Steel.
