Q1. A chef holds a 1 kg bag of flour steady in her hand. Her forearm has a length of 30 cm, a mass of 500 g (uniformly distributed) and the biceps muscle attaches at a distance of 3 cm from the elbow joint. Assume the foreearm is held horizontally and force of the biceps muscle acts vertically. bicep ' 0.0 (weight) Figure 1: A chef holding a bag of our in her hand. (a) Draw a diagram of the forearm showing the forces acting on it that cause a torque at the elbow. (b) Calculate the torque at the elbow due to the bag of our alone. (0) Calculate the torque at the elbow due to the mass of the forearm alone. ((1) Assuming the forearm is in rotational eqilibrium, calculate the force due to the biceps muscle. (e) Would this force be greater or smaller if the chef had a longer forearm of the same weight? Assume the biceps inserts at the same distance from the elbow of 3 cm
