a. What is the ideal mechanical advantage of this system? The inclined plane dimensions are 7.2 meters length and 1.8 meters height.b. What effort force is required to move the 600N create? c. In practice, you need to supply an effort force of 75 N to lift the crate. What is the efficiency?d. How could you redesign this compound machine so that the effort force needed was 50 N in practice? Assume the efficiency is your response from part C no matter what changes you make. Be specific with the changes you propose (if you add pulleys state how many, if you change the inclined plane dimensions state the new dimensions, etc.).
6.4. A force of 300 N is sufficient to keep a 100-kg wooden crate moving at constant velocity across a wooden floor. What is the coefficient of kinetic friction?
I need to lift a large engine block but at my age, I can only create 160lbs of force. I will build a lever to assist me. The fulcrum is placed 1.5 ft away from the 575lb block. How far away will i need to be from the fulcrum to achieve movement of the block?
Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Andy's side?

Fast pls solve this question correctly in 5 min pls I will give u like for sure Sub Find the work done in pumping gasoline that weighs 42 pounds per cubic foot. The top of a cylindrical gasoline storage tank at a service station is 4 feet below ground level. The axis of the tank is horizontal and its diameter and length are 7 feet and 15 feet, respectively. Find the work done (in ft-lb) in pumping the entire contents of the full tank to a height of 3 feet above ground level. (Round your answer to tw
