Determine the location of the sweet spot of the bat shown in the figure (Figure 1). The linear mass density of the bat is given roughly by (0.61+3.3x2)kg/m, where x is in meters measured from the end of the handle. The entire bat is 0.81 m long. The desired rotation point should be 5.0 cm from the end where the bat is held. [Hint: Where is the cm of the bat?

A thin- walled cylinder of radius 50 cm, mass 1.0 kg, is mounted on a frictionless, horizontal axle as in Figure 1 . A light cord wrapped around the wheel supports an object of mass 2 kg. When the wheel is released, the object accelerates downward, the cord unwraps off the wheel, and the wheel rotates with an angular acceleration. Find the angular acceleration of the wheel, , and the tension in the cord.

A baseball bat has a "sweet spot" where a ball can be hit with almost effortless transmission of energy. A careful analysis of baseball dynamics shows that this special spot is located at the point where an applied force would result in pure rotation of the bat about the handle grip. Determine the location of the sweet spot of the bat shown in the figure (Figure 1). The linear mass density of the bat is given roughly by (0.61+3.3x2)kg/m, where xx is in meters measured from the end of the handle. The entire bat is 0.83 m long. The desired rotation point should be 5.0 cm from the end where the bat is held. [Hint: Where is the cm of the bat?] Express your answer using two significant figures.
a bucket of water with a mass of 25 kilograms is lifted from a well by a rope which is wound around a cylinder with a radius of 0.10 meters. A 0.50 meter crank is attached to the cylinder so that it wraps the rope around the cylinder. what is the minimum force that must be applied to the crank to lift the water bucket ?
Jackson finds an old well with a rope, bucket, a shaft that spools the rope, and a large crank wheel that turns the shaft to bring up the bucket of water. The bucket and the water have a total mass of 10.33kg, the shaft has a diameter of 15cm, and the crank wheel has a radius of 0.625m. Ignoring the mass of the rope, use torque to find the tangential force on the crank wheel required to lift the bucket and the water at a constanst speed.

In the figure below, both the ceiling and the ruler accelerate together at 1.6 m/s2 in the +y direction, and the reading to the "new" length of the vertical wire is as indicated. Ignore the effect on the two diagonal wires. Other parameters are below: Weight of the pan = 5 N Weights (or loads) = 74 N Originally, the wire has a length 0.200 cm, and diameter of 2.7 cm. Calculate the Young's modulus of the wire in Pa. NOTES: Use pi = 3.14. Final answer in ZERO decimal place. 4.000 4.100 4.200 4.300 cm

The wheels,axle, and handles of a wheelbarrow weigh W=56N. The load chamber and it’s contents weigh WL=635N.the drawing shows these two forces in two different wheelbarrow designs. To support the wheelbarrow in equilibrium, the man’s hands apply a force to the handles that is directed vertically upward.consider a rotational axis at the point where the tire contacts the ground, directed perpendicular to the plane of the paper.find the magnitude of the man’s force for both designs.
