Key features

• Allows safe and practical experiments into deflections of beams and cantilevers
• Realistic and verifi able experiment results
• Optional Structures Software package for extra ‘virtual’ experiments that simulate and confirm the results from your hardware and allow extended experiments
• Optional unit including Structures Software package for automatic data acquisition and virtual experiments
• One of many interchangeable experiment modules from modern, flexible and cost-effective Structures teaching system

Learning outcomes
• Examination of:

• Beam defl ections
• General bending formulae
• Beam end rotations
• Elastic moduli (Young’s modulus) for various materials

• Typical conditions are:

• Cantilever
• Propped cantilever
• Simply supported beam

Key specifications

• Ten knife-edges with weight hangers and 150 x 10g masses
• Three test beams (1 x aluminium, 1 x steel, 1 x brass)
• Digital defl ection indicator

Description
The experiment hardware consists of a backboard that fixes to the Structures Test Frame (STR1, available separately). Test beams fi t onto the backboard using a rigid clamp and knife-edge supports. Students apply loads at any position using hangers holding various masses. Mounted on a trammel, a digital defl ection indicator traverses the beam. The indicator measures beam defl ection. Scales on the backboard show the position of the indicator, the loads and supports. The lecturer guide provides details of the equipment including sample experiment results. The student guide describes how to use the equipment and gives experiment procedures. For extra ‘virtual’ experiments, can supply the optional Structures Software (STRS), for use on a suitable computer. The virtual experiments simulate the tests you can perform with the hardware.

They also extend the choice of tests beyond that available using only the hardware, for example: higher loads,uniform loads or different test specimens. This extends the student’s learning experience.For automatic data acquisition of your experiment results, can supply the optional Automatic Data Acquisition Unit .

Supplied as standard with the STR2000 is Structures Software that displays and logs your experiment results and gives the extra virtual experiments.
