what I learned from assignment 7 - Torque and Levers
Torque (t)
rotational force
applied around a fulcrum
T = F x d
force x perpendicular distance
newton meter (N•m)
law of the lever
Fe dE = FL dL
only when in equilibrium, the effort torque = the load torque
used for solving any unknown forces/ditances in levers
types of levers
first class
fulcrum is between the effort and load
seesaw, crowbar
second class
load is between the effort and fulcrum
wheelbarrow
third class
effort is between the load and fulcrum
fishing rod, tweezers
effort and load torque calculations
example: camper using a steel bar to lift a trailer
effort force required = 500N
practical applications
wrenches
pliers
crowbars
key takeaways
the torque depends on the force and distance
longer levers = less effort force
