Specification

Basic cantilever beam is the best example so as to demonstrate effect of load so as to generate the strain. Here the fact is very well known that generated strain is directly proportional to load. The setup is provided with loading arrangement for cantilever beam with strain gauges and necessary signal conditioning circuit.

Range of Experimentations

  • Cantilever beam
    • Capacity: 2 kg • Material: Mild Steel
  • Indicator:
    • Least Count: 1 Micro Strain • Digit: 3 ½
  • Weights: Max 2 kg in steps of 100 gm

Specification

Measurement of Torque is a very essential phenomenon, because by nature itself Torque is a very difficult parameter to understand. Also Torque is a very important parameter from Design Engineers point of view. Because it is the key parameter for Hp & other related calculations for Motor or Gear Boxes etc. Here main aim is to demonstrate & explain about what Torque is & then how to measure it.

Range of Experimentations

For all types of Governor.

  • Torque Lever
    • Length: 0.5 Meter • Material: Mild Steel
  • Digital Indicator:
    •` Least Count: 0.1 Kg-M • Digit: - 3 ½
  • Weights: Max 2 kg in steps of 100 gm

Hartnell Governors. Effect of varying the spring

Specification

Here an Acrylic Tank is made / provided as a Main Tank whose Water Level is to be measured. But while forming this Tank two of it walls, which are face to face, are provided with Metal Plates inside. So when the Tank is empty these two Metal Plates along with inside Air, forms a Capacitor. Linear scale is fitted on tank for visual reference.

Range of Experimentations

For the combination of cams and followers provided, the following tests can be conducted.

  • Acrylic Tank: Max reading height: 100 mm
  • Indicator: Least Count: 1 mm Digit: 3 ½
  • Powder coated enclosure.

Specification
