You will see that time 2. There is a very high class mobile% compared to the first time. Why is it that the thickness of the iron has reached the set to make? To compress. When compression is. Unlike glue it cause the beam time 2 Very little strength.
It is evident that the two The class has moved% higher compared with the first. Reason is because the thickness of the steel has yet to be taken to limit the squeeze on complete compression. The glue that causes the second beam has been very little.
Is that a second time. % the class moves very high compared to the first. The cause is because of the thickness of the steel size limit must be made to squeeze, when compressed, glue crack cause beam second.
