About This Product
Before loading, students check that the apparatus, hanger, hook or rod can safely carry 2.5 kg. The weight is added carefully, the system is allowed to settle, and force, extension or balance readings are then taken. It is lifted off with both hands and returned to storage after use, with fingers kept clear of the load. Load-bearing experiments are carried out under teacher supervision.
Frequently Asked Questions
Q1. What needs checking before the weight is added? Make sure the apparatus, hanger, hook or rod can safely support 2.5 kg, and that the setup stands on a stable laboratory bench.
