Data has been gathered from a lifting system used to remove spent RBMK fuel rods from the spent rod pool into long term safe storage. At present the spent rods are winched up from the pool and then lowered into concrete barrels in a second pool.  When it is positioned properly the winch is released and the rod is allowed to drop in.  The following calculation is based on data gathered from the present set up. Time taken to lowered into concrete barrels = 10 Seconds Winch drum diameter = 0.9m Mass of load = 185 kg Initial velocity = 0 m/s Distance travelled = 6m You have been asked to use this information to determine: The final linear velocity of the load The linear acceleration of the load The final angular velocity of the drum The angular acceleration of the drum The tension force in the cable The torque applied to the drum   In determining the above quantities, you should clearly state the formulae used and apply dimensional analysis techniques to show that all values/units used…

The uniform 52-kg slender bar is initially at rest on a smooth horizontal plane when the forces are applied. If P₁ = 20 N and P₂ = 86 N, they are constant and are always perpendicular to the slender bar, determine angle (in degree) when time t = 0.40 s has passed. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. 0.75 m P₁ Your Answer: Answer 1.75 m 0.5 m P₂
