What is mechanical advantage?Show answer
A wheelbarrow and a bottle opener have a large mechanical advantage, letting a small effort move a large load. A third-class lever has an MA less than 1 (the effort is larger than the load) but gains speed and range of movement instead, which is why tweezers and the forearm are third class.
What is q1?Show answer
Which class of lever has the pivot between the effort and the load? [1 mark]
What is q2?Show answer
State the equation for a moment. [1 mark]
What is q3?Show answer
A force of 40 N acts 0.3 m from a pivot. Calculate the moment. [2 marks]
What is q4?Show answer
A lever balances a 100 N load with a 25 N effort. Calculate the mechanical advantage. [2 marks]
What is q5?Show answer
Give one use of a reverse-motion linkage. [1 mark]
