What is the ideal mechanical advantage of a screw whose head has a diameter of 0.812 cm and whose thread width is 0.318 cm?

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.

A bolt has a requirement of being tightened to 38Nm. You pull on the end of a 25cm wrench at an angle of 120 degrees.To the radial arm line. What is force of the pull needed?

A ruler with the length of 100 cm and mass of 100g has the pivot point at 35 Cm. Jason suspends an object at 10 cm mark and the system stayed balanced. What is the object mass in grams?

An aero engine has Hub diameter of 0.36 and a tip diameter of 0.70, what is the radius of the blades

A weight of 6 N is located 8 cm from the fulcrum on the beam of a simple balance. What weight should be placed at a point 4 cm from the fulcrum on the opposite side in order to balance the system?

A particular bolt needs to be tightened with a torque of 20 N m to ensure it does not come loose. What minimum force must be applied to a 30 cm long wrench handle to set the proper torque?

A 9.1 Newton weight is attached to a 9.9 cm from the fulcrum of a balance beam. What weight should be placed 3.4 cm away from the fulcrum on the other side of the beam in order to balance of the system?

A seesaw is a flat board that is balanced on a fulcrum (point of balance). When the weight at either end is equal, the seesaw is balanced and both ends are at the same height. When weight is added to either side, the balance will tilt in that direction. To prevent the balance from tipping, the location of the fulcrum must be moved to accommodate the difference in weights placed on each end. A playground equipment company wants to produce a seesaw that will be perfectly balanced when an adult and a child are on either end. The company estimates that an adult, on average, weighs four times as much as a child. The length of the seesaw is 10 feet. C A { 01 2 3 4 5 6 7 8 9 10
