Twist & Bending Machine Model MT 090
Twist & Bending Machine Model MT 090
Sci-tech Twist & Bending Machine Model MT 090 is a combined apparatus for the demonstration of both twist and bend to be used in the laboratory or as a complement of the theoretical study about twist and bend. Its size and weight facilitate its transport and make it ideal to develop the practical exercises.
The MT 090 unit consists of two transverse guides on which the beam supports slide. The supports can be placed different distances apart, thus the student can check the effect produced by this variation in the deformations of the beam subjected to flexion or torsion efforts.
In flexion experiments, the student will be able to calculate the Elasticity Modulus of different materials, demonstrating the relation load- deformation.
In torsion experiments, the student will also be able to check the relation load-deformation and get the Rigidity Modulus of different materials.
The test pieces used for flexion experiments are made of stainless steel with different rectangular cross sections. Therefore, circular section test pieces of different materials can be used.
The test pieces used for torsion experiments are made of different materials and with circular cross sections, what will allow the student to compare the Rigidity Modulus of different materials.
A dial gauge with its assembly accessories is supplied to measure the beam deformations both in flexion and torsion experiments.

Item Description
Torsion is a type of effort that appears when applying a momentum or force on a bar or element. The transverse sections of the bar suffer a twisting around an axis normal to its plane where tangential efforts analogous to the simple shear efforts are developed.
Bending is another type of effort (deformation) that appears in a long structural element in a direction perpendicular to its longitudinal axis. Bending moments are caused by the application of loads normal to the longitudinal axis of the element, generating a bend.
