SM1301 Bending and Torsion Testing Machine
This is a compact tabletop testing machine that conducts deflection tests and torsion tests on round bars. It comes with various test specimens and a weight set necessary for experiments, allowing immediate experimentation according to the experimental manual. It has been specially designed as an educational testing device. Deflection Test Using rectangular cross-section test specimens, deflection experiments and theoretical verification are conducted for simply supported beams, fixed beams, one-end fixed and other-end hinged beams, and cantilever beams. Loads are applied using a weight hanger, and the deflection of the beam is measured with a dial gauge. Six types of soft steel test specimens with different cross-sections are included, allowing verification of deflection and Young's modulus throughout the tests. Torsion Test Rotational torque is applied to φ8mm round bar test specimens made of three materials (soft steel, aluminum, brass) to measure the angle of twist. A weight hanger is suspended 100mm away from the center of the specimen to calculate torque from the weight and distance. The angle of twist can be measured from the rotation of the dial gauge (1 rotation = 1 degree). The elastic coefficients of each material can be verified, and the deformation can be observed.
