Continuous and Indeterminate Beams Apparatus a fourth pier clamps a cantilever or the fixed end of a beam. A double pulley assembly provides vertical loading of the beam. Each pier caters for simply supported, or Continuous and Indeterminate Beams Apparatus and their beam attachments allow for rotation but no vertical movement during testing. Point loads and uniformly distributed loads can be applied to the beams using the set of calibrated weights and hangers supplied. Sinking supports can be studied due to the fact that each reaction pier has a height adjustment system and integral dial gauge attached. Three piers measure vertical reaction forces with their integral load cell which connect directly to the Interface.

The designed for training in ventilation engineering. The individual components in the ventilation system are fitted with pressure measuring glands. The power consumption of the fan is indicated on the switch cabinet using a voltmeter and an ammeter. For this purpose, an inclined tube manometer with 2 measuring ranges and a digital handheld unit for the measurement of the air velocity are included, along with numerous other components. Once the trainee has built a ventilation system independently, the effects of bends, branches, regulator flaps on the airflow rate, the air velocity, as well as the pressure loss can be investigated. The components are the same as those used in ventilation engineering.
