A stepladder consisting of two legs pinned together at C is resting on a rough floor. The uniform legs AC and BC weigh 15 kg and 8 kg, respectively. The coefficient of static friction at A and B is 0.48. What is the maximum weight of the worker (in kg) to avoid slipping while changing the light-bulb? (Hint: Only one leg will slide at a time) *Write your answer in two decimal places. 1.4 m 60° 60° 4.8 m

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Bucket A and block C are connected by a cable that passes over drum B. Drum B rotates slowly counterclockwise and the coefficients of friction at all surfaces are μ = 0.35 and μ = 0.25. Given: W= 120 kg. m B W 30° Determine the smallest combined mass m of the bucket and its contents for which block C will remain at rest. The smallest combined mass m of the bucket and its contents for which block C will remain at rest is 28.896 kg.

In this assignment, the radius refers to the distance between the location where the force is applied and the axis of rotation. A ruler is initially at rest when a student briefly exerts a downward force on the right end, as shown. The magnitude of the force exerted by the student is less than the weight of the ruler. Assume that the pivot point is frictionless. Answer the following questions based on this description. Part A: 1. While the hand is pushing, but before the ruler begins to move, the tangential acceleration of the ruler is 2. While the hand is pushing, but before the ruler begins to move, the centripetal acceleration of the ruler is 3. While the hand is pushing, but before the ruler begins to move, the angular acceleration of the ruler is 4. At the instant the hand has stopped pushing, the tangential acceleration of the ruler is 5. At the instant the hand has stopped pushing, the centripetal acceleration of the ruler is 6. At the instant the hand has stopped pushing, the…

Part A A stone is suspended from the free end of a wire that is wrapped around the outer rim of a pulley, as shown in the figure (see the figure (Figure 1)). The pulley is a uniform disk with mass 11.6 kg and radius 48.0 cm and turns on frictionless bearings. You measure that the stone travels a distance 12.4 m during a time interval of 3.50 s starting from rest. Find the mass of the stone. Take the free fall acceleration to be 9.80 m/s.

In 1956, Frank Lloyd Wright proposed the construction of a mile-high building in Chicago. Suppose the building had been constructed. Ignoring Earth's rotation, find the change in your weight if you were to ride an elevator from the street level, where you weigh 701 N, to the top of the building. Number i Units î
