Tensile Testing Machine

Tensile Testing Machine Points : Tensile Testing Machine Testing machines: Two types of testing machines commonly employed are:
(i) Manually operated
(ii) Power operated. (i) Manually operated The manually operated testing machine is used where low capacity is necessary works on the principle of screw and lever system.

(ii) Power operated The power operated type machine type is used where large capacity is required hydraulically operated testing machine. It consists of a clients a which a piston moves under the action of certain pressure. This pressure depends of oil which enters the cylinder. The force on the piston can be increase increasing the oil pressure. The oil pressure and hence the load can be read true gauge calibrated in N or kg.
