To solve this question, you need to complete the previous one first. You are in the same conditions.
Two hangers are made up of cold-drawn steel with an ultimate tensile strength of 400 MPa. The Young's modulus value of the steel is 200,000 MPa. Both hangers have the same cross-sectional area of 100 mm^2.
The hangers are supporting a rigid plate and mass (M) of 15 kg.
Calculate the mass (M) required to fail the hangers if the mass is now dropped from a height of 1 m as shown in Figure B1b (from the previous question).
M = 10 kg
M = 12 kg
M = 14 kg
M = 16 kg
