Two painters stand on a 10.0mlong plank of mass 300 kg. The plank rests on two pillars separated by 6.00m. Danny has a mass of 92.0 kg and stands 3.00m from the left end of the plank and Jerry has a mass of 68.0 kg and stands 1.50m from Danny. Assume that the plank is not nailed to the pillars (the plank only rests on top of pillars). Danny = 92 kg Jerry = 68 kg 3m mass plank = 300 kg 1.5 m 2m 6m 2m Assuming both painters are now off of the plank determine what maximum amount of mass can be placed at the right edge if the plank is not to tip over.
A woman doing core exercises is in a “plank position,” as shown in the diagram below. The jointwhere the spine meets the pelvis is the pivot, with the legs on one side and the upper body on theother. It is the abdominal muscles that keep the two segments from bending away from each other.The contact force at her feet is 230.0 N, and the mass of the lower segment of her body is 30.61 kg.What is the tension in her abdominal muscles that keeps her body in static equilibrium? Note:1. The object is the lower portion of the person’s body.2. The object interacts with the following things: The Earth exerts a gravitational pull (FG)verticallydownwards on this portion of their body. The feet are touching the floor, so there is a normal force(n) there. The abdominals pull (T)towards the right to balance the torques due to the other forces.This presses the pelvis into contact with the lumbar vertebrae.
A gymnast rises onto her toes, as shown in the picture on the right. The floor pushes up on the ball of her foot with a force of N=313 N. If 0=56.0°, what are FH the forces in her heel (TH) and ankle joint (T), and what is the angle o? Answers: TH=481 N; T,=761 N; b=20.7° N, 0. 4.25 cm 9.66 cm 5.

Three children are trying to balance on a seesaw, which consists of a fulcrum rock, acting as a pivot at the center, and a very light board 3.2 m long. Two playmates are A m = 45 kg |x Part A B m = 35 kg m = 25 kg already on either end. Boy A has a mass of 45 kg, and boy B a mass of 35 kg. Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw? Express your answer to two significant figures and include the appropriate units.

A large airplane typically has three sets of wheels: one at the front and two farther back, one on each side under the wings. Consider the Boeing 787 "Dreamliner", with a mass of 175000 kg. In this particular model, the distance from the front wheels to the rear set of wheels is 19.5 m (b) How much force, in meganewtons, does the ground exert on the front set of wheels?

when one boy is sitting 1.2 m from the center of a see-saw, another boy must sit on the other side 1.5 m from the center to maintain an even balance. However, when the first boy carries an additional weight of 14 kg and sit 1.8 m from the center, the second boy must move to 3 m from the center to balance. Neglecting the weight of the see-saw, find the weight of the heavier boy.
