I got question 5 and 12 wrong. Question 5 was a 3 class lever has the _________ in the middle. I picked load. It was effort. The other was a crowbar is a class____ lever. It was 1.
ReplyDeleteKaitlyn
The question I got wrong was Question 11/13. The question was “What
ReplyDeletekind of lever system is a hockey stick?”. I put Class 2 but the real answer
was Class 3 because the hockey stick is supported by the Fulcrum ( you ) and the effort is you moving it. The load must be at the other end from the Fulcrum so as to use the effort to move the load ( puck ). I learned that levers were first described about 260 BC by the ancient Greek mathematician Archimedes (287-212 BC).
Amelia
The question I got wrong was number 13. The question was ‘’ The
ReplyDeletefarther from the fulcrum the effort is, the less effort is required to
lift the load. ‘’ I clicked false but the answer was true. To decrease the force needed, the distance between the fulcrum and the effort must be increased. To increase this distance, the load must be close to the fulcrum and the effort must be used far from the fulcrum. If you increase the mechanical advantage you can use less effort to move the load.
