A painter leans a ladder against a wall at an angle of 60˚ to the ground. (Assume the ladder is uniform and the center of mass of the ladder is located at the middle of the ladder.) The ladder is 3.00m long and has a mass of 10.0kg. The person has a mass of 90.0kg. How far up the ladder can the painter climb before it slips if the coefficient of friction is 0.45?
9.1 A ladder of length L, but negligible mass, leans against the side of a house, with the bottom of the latter a distance B from the wall. The coefficient of static friction between the bottom of the ladder and the ground is us. Assume that the contact interaction between the top of the ladder and the wall is frictionless (but it still exerts a normal force on the ladder). A person of mass m climbs a distance D up the ladder, as shown. (a) Draw a free-body diagram for the ladder. (b) What is the maximum distance Dmax that the person can climb up the ladder before it starts slipping? Express your result in terms of L, B and us only. Hint: Your result should be independent of m. Check: For B = (3/5)L and us (c) Evaluate your result from part (b) for L = 0.5 you should find Dmax = 0.667L. 5 m, B = 2.5 m and 0.4.
Body U with mass 5m is stacked on the top body W withmass m, and released. The bodies are in contact along thefrictionless interface at 45 to the vertical. The body U isin contact with the frictionless vertical wall. Body W lieson the floor with coefficient of friction u. Relevantdimensions are shown in the figure. Express the results interms of given quantities: m, g, h and u. Body U must stay in contact with the wall. Using the equations of motion for the two bodies compute the accelerations during the motion while in contact.
. The forces exerted by the bicep muscle and acting on the elbow when a 12 kg barbell is being curledcan be modeled based on the diagram above. The bicep muscle can be treated as a vertical cable. Themass and length of the forearm are 2 kg and 32 cm, respectively. The center of mass of the forearm is adistance of 14 cm from the point P, while the bicep connects to the forearm at a point 4.5 cm from P.a) Determine the tension in bicep muscle and the force of the humerus acting downward on the elbowat point P. b) Assuming the tension in the bicep muscle continues to be oriented vertically, determinethe tension in the bicep muscle and the force acting at P after the barbell has been raised by an angleof 30 relative to the horizontal.
A bean of wood with negligible mass and the lenght 5.0 m is placed on a tirangular support. A mass of 9.5 kg is hanging on the left end of the beam, and a box with mass 23kg is placed on the beam. In order to prevent the beam form moving and to keep it in equilibrium, a person has to support the beam at the right end. IF the distance from the pivot to the hanging mass is 1.2 m, and the distance from the pivot to the point where the force from the box is applied on te beam is 2.3 m, with that magnitude of force F in the unit N , does the person have to hold the beam tokeep the equilibrium?
