Question

You are part of a design team that works on designing a chair. One day, a teammate hands you a scaled model of a chair 20 cm high and asks you to check if the actual chair would be sturdy enough. Your teammate wants you to check if the chair can withstand a heavy load. You are told that the scaled model is made of the same material as the actual chair, and you have checked that the actual chair is supposed to be 1.5 m tall. According to the specification, the chair is supposed to remain firm even when a 150 kg load is placed on it. You decide to test the team’s design by placing a test load on the scaled model and see if the model would remain firm. Based on the information you have, what should be the mass of the test load?
