A 1 555-kg automobile has a wheel base (the distance between the axles) of l = 2.85 m. The automobile's center of mass is on the centerline at a point 1.35 m behind the front axle. Find the force exerted by the ground on each wheel. Part 1 of 3 - Conceptualize Since the center of mass is located in the front half of the car, there should be more force on the front wheels than the rear ones. The sum of the wheel forces must equal the weight of the car. Part 2 of 3 - Categorize Use the figure as a force diagram. Apply Newton's second law and sum the torques to find the unknown forces. l Part 3 of 3 - Analyze The torque about the front axle is zero, so we have Στις = 0 = (d Fg) - l (2F₁). Thus the force at each rear wheel is given by d F F₁ = 2Ff g || d 21 2F, m)(1. X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step da N. Since the sum of the wheel forces equals the weight of the car, we have 2F₁ + 2F₁ = Fg.…
Direction: Solve the following problems completely. Include FBD. Determine the distance s to which the 70 kg painter can climb without causing the4m ladder to slip at its lower end A. The top of the 12 kg ladder has a small roller andat the ground the coeffiecient of static friction is 0.2. The center of mass of the painteris directly above herfeet.
A ladder of length 2L and mass M is positioned on level ground leaning against a wall such that the angle between the ladder and the horizontal is a. The coefficient of static friction between the ladder and the wall and between the ladder and the ground is jistatic = 0.66. The centre of mass ofthe ladder is halfway along it. Draw a diagram indicating all the forces acting on the ladder, and state what each force represents. Also show the direction of the a- and y-axes you will use.
4. Orin and Ann, two paramedics, rush a 60.0 kg man from the scene of an accident to a waiting ambulance, carrying him on a uniform 3.00 kg stretcher held by the ends. The stretcher is 2.60 m long and the man’s center of mass is 1.00 m from Ann. How much force must Orin and Ann each exert to keep the man horizontal? a. Orin = 230 N, Ann = 388 N b. Orin = 201 N, Ann = 411 N c. Orin = 241 N, Ann = 377 N d. Orin = 141 N, Ann = 477 N e. None of the above
It is sometimes important to determine the location of a person’s center of gravity(which coincides with the center of mass because the gravitational force is uniform at the scale of the human body). This can be done with the arrangement shown intheFigure below. A light (negligible mass) plank rests on two scales that read Fg1=380 N and Fg2=320 N. The scales are separated by a distance of 2.00 m. How far from the woman’s feet is her center of gravity?
