A clever witch is social distancing during trick-or-treating by sticking her pumpkin-shaped bucket full of candy on the end of her broomstick. Her broomstick has a length of L = 1.2 m and she holds it Broomstick ly. The broomstick has a mass of 1.10 kg and the pumpkin has a mass of 2.4 kg. The witch holds her hands a distance of d = 0.80 m apart. L d. What is the force from the hand on the end of the broom? This is the hand on the left in the figure. FL = What is the force from the hand closer to the middle of the broom? This is the hand on the right in the figure. FR = N

Wolverine has an arm that is 1[m] long and claws that are 0.5[m] long. He's trying to knock over a wall. His shoulder can exert a torque of 1,500[N-m].

A 480-N force P is applied at point A of the bell crank shown. If a1= 20°, a2= 35°, a= 210mm and b= 70mm, Compute the moment of the force P about O in N.m unit P 0Tーーューー- a 48° b. Yanıt: Determine the magnitude of the smallest force Q (in N unit) applied at B that has the same moment as P about O.

A diver off the high board imparts an initial rotation with his body fully extended before going into a tuck and executing three back somersaults before hitting the water. If his moment of inertia before the tuck is 16.9kgm2 and after the tuck during the somersaults is 4.2kgm2 , what rotation rate must he impart to his body directly off the board and before the tuck if he takes 1.4 s to execute the somersaults before hitting the water?
