Check In the construction of railroads, curvature of the track is measured in the following way. First a 100.0-ft-long chord is measured. Then the curvature is reported as the angle subtended by two radii at the endpoints of the chord. (The angle is measured by determining the angle between two tangents 100.0 ft apart; since each tangent is perpendicular to a radius, the angles are the same.) In modern railroad construction, track curvature is kept below 1.40°. What is the radius of curvature of a "1.40° curve"? 100 ft ft

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.
Why is the value negative for the radius of the wheel in vector form?
A woman applies a torque to a nut with a wrench 0.250 m long. Because of the cramped space, she must exert a force upward at an angle of 70.0° with respect to a line from the nut through the end of the wrench. If the force she exerts has magnitude 46.0 N, what magnitude torque (in N · m) does she apply to the nut? (Assume that the force is applied at the end of the wrench.)
