Problem 5. Hauling a boat. You have a new 1000 lb boat that you are going to need to pull out of the water across a (slippery) File Preview e by hooking a winch to it. The shore is sloping up at an angle of 20 degrees. You need to figure out if you can pull it up with a hand winch, and if so, what kind should you buy. You have the choice between a 4 inch diameter winch or a more expensive 8 inch diameter winch. Both have 1 ft long handles. boat launch winch winch handle (a) Look closely at the diagram of the winch. How does the force you apply to the handle relate to the force the cable can exert on the boat (mathematically)? Hint: the size of the handle and the winch are important. (b) Draw a force diagram for the boat. What is the magnitude of the tension in the cable required to move the boat? (c) Will you be able to drag your boat up the slope by hand with either or both winches? Make a reasonable estimate of how much force a human can provide to the winch handle

A 3.00-kg stone is tied to a thin, light wire wrapped around the outer edge of the uniform 8.00-kg cylindrical pulley. The inner diameter of the pulley is 55.0 cm, while the outer diameter is 1.00 m. The system is released from rest, and there is no friction at the axle of the pulley. a) Find the acceleration of the stone and the tension of the wire. b) Find the angular acceleration of the pulley.
When you carry shopping bags, rather than grasp the handles with your hand as in Q8.14a, you might choose to put them over your arm and slide the handle toward your elbow as in Q8.14b. Explain why this leads to less muscle effort to carry the bags and less force in your elbow joint.

How do you solve problem? I'm confused about which equations to use and which variables go where. How should I think about what is going on? You have a pulley 14.6 cm in diameter and with a mass of 1.9 kg. You get to wondering whether the pulley is uniform. That is, is the mass evenly distributed, or is it concentrated toward the center or the rim? To find out, you hang the pulley on a hook, wrap a string around it several times, and suspend your 1.2 kg physics book 1.5 m above the floor. With your stopwatch, you can find that it takes 0.62 s for your book to hit the floor. Use g=9.8 m/s2. a) What is the moment of inertia if the pulley is uniform? b) What is the actual moment of inertia of the pulley based on your measurement? c) Is the pulley uniform (within 1% of uniform), is the mass of the pulley concentrated toward the center, or is the mass concentrated toward the rim?
3.) A cube of brass has sides of 0.12 m. a. Draw the situation. b. Determine the applied tangential force to displace the top of the block 1.2 x 10-5 m given that Sbrass = 3.5 x 101⁰ N/m².
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…
A group of physics students, each of whom can pull with 100lb of force, is planning to topple a 9600lb statue that the school built for the meanest teacher. Assume the statue does not slide.Answer all questions relative to the rotation point. How much torque is caused by the statue's weight? How much tension must the students generate to "barely balance" the statue? What is the minimum number of students (whole number) needed to topple the statue?
