- The bar is 10 m long. A mass of a 40 kg placed at a 9m from left end of bar. Where should a 60kg mass be placed to balance the bar?You hang a mass of the right side of an equal arm balence and then pull on the hanger with your hand to keep it balanced. (a) if you pull on the left side of the balance do you have to pull up or down to keep the balance in equalibrium? b) if you pull on the right side of the balance do you have to pull up or down to keep the balance in equalibrium?Calculate the minimum diameter required of a 6-foot tension rod required to handle a load of 13,613 lbs, with an ultimate tension stress of 112,224, and a safety factor of 4.
