Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the surface of the door. One child pushes with a force of 18.5 N at a distance of 0.625 m from the hinges, and the second child pushes at a distance of 0.47 m. a) What is the magnitude of the force, in newtons, the second child must exert to keep the door from moving? Assume friction is negligible.  F2 =

In the World's Strongman competition there is a deadlift event where a constant must raise a heavy crate. Use the diagram to determine how much force must be applied to lift a 3000 lb crate,  According to the diagram, the pivot is located 3 feet away from the crate, on the left side of the plank. The whole plank measures 15 feet long.  Pivot = x X_________________I     CRATE     I_____________________________________________  <-----3 ft ------>            Fw  (going down, from crate                                 ^ <------------------------------------------------ 15 ft ----------------------->F (going up)

A 14.0 m uniform ladder weighing 480 N rests against a frictionless wall. The ladder makes a 55.0°-angle with the horizontal. (a) Find the horizontal and vertical forces (in N) the ground exerts on the base of the ladder when an 850-N firefighter has climbed 4.10 m along the ladder from the bottom. horizontal force magnitude 342.35 direction vertical force magnitude direction towards the wall up m N ✪ N (b) If the ladder is just on the verge of slipping when the firefighter is 9.10 m from the bottom, what is the coefficient of static friction between ladder and ground? (c) What If? If oil is spilled on the ground, causing the coefficient of static friction to drop to half the value found in part (b), what is the maximum distance (in m) the firefighter can climb along the ladder from the bottom before the ladder slips?

The image below depicts the Apollo 16 Lunar Module (LM) on the moon's surface. The diagram to the right is a model of one of the four landing gear assemblies. Determine the force supported by members AB, AC, and AD under the assumption that the weight of the LM is uniformly distributed by all four landing gear assemblies. Use Mathematica or an online calculator such as the WolframAlpha 3 Equation System Solver to solve the 3 x 3 system of equations that you will end up with.

An 88 kg person stands on a uniform ladder 4.0 m long, that weighs 100 N, as shown in the figure(Figure 1). The floor is rough; hence, it exerts both a normal force, f1, and a frictional force, f2, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force, f3. Figure f₁ mg f3 a-3.8 m 1 of 1 Part A Using the dimensions given in the figure, find the forces exerted on the ladder when the person is halfway up the ladder.

A setup similar to the one shown in the figure below is often used in hospitals to support and apply a horizontal traction force to an injured leg. (Let m = 5.25 kg and 8 = 75.0°.) (a) Determine the force of tension in the rope supporting the leg. N (b) What is the traction force exerted to the right on the leg? Additional Materials еВook

How much tension must a 28.0 m long wire be able to exert without breaking when it is used to hang an iron sculpture that weighs 2784 N? The wire must be attached to two anchors in the ceiling 16.1 m apart.

The steel I-beam in the drawing has a weight of 7.74 x 10³ N and is being lifted at a constant velocity. What is the tension in each cable attached to its ends? 70.0⁰ 70.0⁰ I-beam
