The testing machine is a huge screw-power press fitted with a massive platform scale for weighing the load applied. The screws which exert pressure can be seen in the cut. Load is applied and weighed until t h e beam collapses, and the deflection is measured by means of a micrometer dial shown at the middle of the beam.

Delicate micrometers are used t o measure the stretch along the under side and the compression along the upper side. • .,-p T-CH OP1" 4-3 ._ U CD o3 O © M 4J ^O T E S T OF A R E I N F O R C E D C O N C R E T E BEAM MATERIALS TESTING LABORATORY
