Two construction workers, Wallace (75.0 kg) and Xavier (80.0 kg), are on a suspended scaffold, The scaffold is made of a uniform horizontal plank with mass 150.0 kg and length 3.80 m, supported on either end with vertical cables. Each cable can withstand a tension of 3185 N without snapping. Wallace and Xavier need to bring some equipment on the scaffold with them, place it anywhere, and be able to stand anywhere on the scaffold safely. a) What is the maximum mass of equipment they can bring on the scaffold with them? (Hint: assume everything is in the worst place possible.) They bring 50.0 kg of equipment and place it in the middle of the scaffold. Wallace stands 1.00 m from the left end and Xavier stands 1.20 m from the right end. b) What is the tension in the left cable? c) What is the tension in the right cable
