Why are the handles of a pair of scissors smaller than its blades while the handles of a pair of shears longer than the blades? Both are 1st class lever.
STATE THE PRINCIPAL OF MACHINES.
A man applies a force of 120 N to lift a heavy body of weight 80 N by a crowbar of length1.25 m. What is the length of the effort arm?
What do you mean by"load*load arm=effort*effort arm=mechanical advantage of a machine"?
The efficiency of a machine is 60%. If the work done on the machine is 660 J, then what is the work done by the machine
how do you feel when you see the beauty of rainbow in the sky?express your feeling in the form of asong or a poem
Cananyone say why we use a fire tong or tweezers although we do not get any mechanical advantages from them?
PLZZ. FAst haVE TO COPLETE... ALONG WITH TEST...

Expert Sir, please clarify-Why are the handles of a pair of scissors smaller than its blades while the handles of a pair of shears longer than the blades? Both are 1st class lever.
Wheel and axle is which type of multiplier force multiplier or speed multiplier ????
Which type of multiplier is wheel and axle force multiplier or speed muliplier????
How we can canculate mechanical advantage of inclined plane????
A heavy rock A is lifted using a lever of length 80 cm such that the fulcrum is situated at 30 cm from the load. If the fulcrum is shifted 10 cm away from the load then by what percentage the mechanical advantage changes?
Two machines A and B have efficiencies in the ratio 3:4. If the work done on machine A is 1200 J and on machine B is 1800 J, then what is the ratio of the work done by A to B
a man applies force of 120 N to lift a heavy body of weight 80 N by a crowbar of length 1.25m . What is the of the effort arm?
I was looking at the chapter of inclined plane or wedge in the topic test (no.5) it said that a winding staircase is an example of a ramp .How is a winding staircase an example of a ramp?Since it is winding I was thinking it could be an example of a screw.
what are lower and higher machins
Can you give an example of an inclined plane
how to find the % of the mechanical advantage???????????????
what is the power of most strongest magnet
A heavy rock is lifted using a lever of length 80cm such that othe fulcrum is shifted 10cm away from the load then by what percentage the mechanical advantage changes?
input energy is the energy put by the load?
Why do we use a fire tong or tweezers if we do not get any mechanical advantage from them?
what are terminologies?
Two machines have efficiency in the ratio of 3:4. If the work done on the machine A is 1200J and on machine B is 1800J , then what is the ratio of the work done by A and B?
