A pulley system is used to raise a shipping container from the dockto a cargo ship. An effort force of magnitude 6.8 x 10*4 N isrequired to lift a load of mass 3.5 x !0*4. the effort force moves54 m while the load is raised 8.7 m.

(a) Calculate the magnitude of the load force
(b) Calculate the IMA, the AMA and the percent efficiency of thepulley system

An emergency crew is using a plank as a 1st lever to raise one side of a car off the road. The fulcrum is a large block of wood. The magnitude of the load force is 5200 N and that of the effort force is 650 N; the load arm and effort arm are 0.40 In and 3.6 m, respectively. Calculate the

a) AMA

b) IMA

c) percent efficiency of the plank

A lever, 3.0 m long, is used to lift a load of 900 N.

a. What is the minimum force needed to lift the load if it is 1.0 m from the fulcrum? Assume 1st class lever and 3.0 m between the applied effort and the load

b. What is the minimum force needed to lift the load if it is 1.0 m from the fulcrum? Assume 2nd class lever the fulcrum is 0.30 m from the end

c. What is the minimum force needed to lift the load if it is 3.0 m from the fulcrum and the effort is 1.0 m from the fulcrum? Assume class 3rd class lever

What were the causes and consequences of the American Civil War? With reference to the period between 1830 and 1877, explain what caused the tensions and the break between the North and South, how the war affected both sections of the country, and how and why Reconstruction did (or did not) transform the South.
