Auto Test Machine enables us to test the resistance and the stress of certain materials. The testing method is to apply accelerated pressure on the upper and lower surface of the material. As the speeding pressure goes high, the piece of the material broke into parts. At this stage, the machine stops pressing and records the value as the maximum tolerance achieved.

1 - " Enables us " -- or --- " Enables you "
2 - " the method of testing is TO APPLY " --- or --- " is BY APPLYING "
