CALCULATION R Where: M- Moment I- Area Moment of Inertia (kg/m)-x (m) 12 o Stress (MPA) ye= Thickness h/2 (mm) E- Young's Modulus R- Radius of Curvature (mm) If an arm is subjected to a bending moment, we can use Equation (1) to calculate (bending stress, bending amount, bend radius of the bar, modulus of elasticity of the bar material). By knowing the magnitude of the effective moment (M) and the moment of inertia of the rod section (I), and in the given case in the experiment, the radius…
A) Suppose you need to design a tension test machine capable of testing specimens that have nominal ultimate stresses as high as σu = 100 ksi . How much force must the machine be capable of generating? Assume the testing specimen has the ASTM shape shown. B) If the maximum nominal strain is ϵf = 0.7 just before the test specimen fractures and the test machine operates by moving only one grip, how far must that grip be designed to travel? The total length of the deforming part of the specimen is 3 in .
