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 wheelbarrow is a lever used to move heavy objects or materialsfrom one place to another. The load force for the materials. Draw awheelbarrow with a wheel and axle, bucket, handle. This is what isgiven 0.45 m, 250N and 1.4 m

(a) label the fulcrum, effort force, effort arm, and load arm. Whatclass lever is a wheelbarrow?

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

<p>Draw a wheelbarrow</p>
<p>The load force for the material acts through the middle.Lable the fulcrum, effort force, effort arm and load arm. Whatclass of lever is a wheelbarrow?</p>
<p>Calculate the magnitude of load torque and the magnitudeof the effort force required to support the wheelbarrow if theeffort force is placed at the end of the handle.</p>
<p>This is what is given 0.45 m, 250 N and 1.4m</p>
