Problem 4: You have been hired to design a family-friendly see-saw. Your design willfeature a uniform board (mass M= 9 kg, length L =12 m) that can be moved so that the pivot is adistance d from the center of the board. This will allow riders to achieve static equilibrium even ifthey are of different mass, as most people are. You have decided that each rider will be positionedso that his/her center of mass will be a distance xoftet = 21 cm from the end of the board whenseated as shown.You have selected a child of mass m = 23 kg (shown on the right), and an adult of mass n=4 timesthe mass of the child (shown on the left) to test out your prototype.XffsetXoffsetPart (a) Determine the distance d in m.d =sin()cos()tan()79HOMEacos()sinh()cotan()asin()4atan()acotan()123cosh()tanh()cotanh()+ENDODegrees O RadiansVol BACKSPACE DEL CLEARSubmitHintFeedbackI give up!Part (b) Determine the magnitude of the force exerted on the pivot point by the see-saw in N.

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. Since the floor is rough, it exerts both a normal force N1 and a frictional force f1 on the ladder. However, since the wall is frictionless, it exerts only a normal force N2 on the ladder. The ladder has a length of L = 4.4 m, a weight of WL = 53.5 N, and rests against the wall a distance d = 3.75 m above the floor. If a person with a mass of m = 90kg is standing on the ladder, determine the following. (a) the forces exerted on the ladder when the person is halfway up the ladder (Enter the magnitude only.) N1 = ? N N2 = ? N f1 = ? N (b) the forces exerted on the ladder when the person is three-fourths of the way up the ladder (Enter the magnitude only.) N1 = ? N N2 = ? N f1 = ? N
A uniform 10.0 m ladder of weight WL=375 N leans against a frictionless wall. There is a force of static friction between the floor and the bottom of the ladder. A person weighing Wp stands 7.4 m between the bottom of the ladder. Draw a free body diagram for the ladder. Draw a torque diagram for the ladder. Determine the force that the wall exerts on the top of the ladder. Determine the force of static friction exerted on the ladder by the floor.
A 5.2-m ladder rests against a wall as shown. The ladder has a mass of 27.6 kg. A 56.3-kg person stands on the ladder at a distance of 3.6 m from the bottom of the ladder. The foot of the ladder is 1.9 m from the bottom of the wall. Assume there is no friction between the ladder and the wall so that the force of the wall on the ladder is acting only in the horizontal direction. However, there is a friction force between the ladder and the ground. 1.) What is the force, in N, exerted by the wall on the ladder?

The horizontal distances between the center of mass of the brick and the centerlines of the cylinders are d,for cylinder A and dg for cylinder B. (c) What is the ratio d,/dg? com of brick
1. The figure below shows the normal configuration of the head with proper posture. The center of mass for the weight of the skull is labeled W and the muscles that attach to the back of the skull are labeled M. Assume all quantities are correct to 2 significant figures. M W a) Determine the mechanical advantage of the skull muscles when d₁ 20 mm and d₂ = 26 mm. Hint: Which force on the fulcrum (rotation point) is the effort, and which is the load? Enter to 2 significant figures Mechanical Advantage: b) Improper posture and positioning of the head can lead to muscle tension headaches. If the head begins to shift forward while studying or reading, the center of mass moves further from the fulcrum or pivot point. It is a subtle change, but the figure below shows the head shifted forward. The center of mass for the weight of the skull is labeled W and the muscles that attach to the back of the skull are labeled M. Determine the new mechanical advantage of the skull muscles when d₁ = 16 mm…
To get up on the roof, a person (mass 87.0 kg) places a 5.60 m aluminum ladder (mass 14.0 kg) against the house on a concrete pad with the base of the ladder 2.00 m from the house.
