If 500 Joule of energy is given to the machine. Effort (E): An external force applied to a simple machine to overcome a load is called the Effort. Unlike a long lever arm which transmits a smaller force but the amplitude of its displacement is larger. What is its output? Sol: Efficiency (p) = 60%, Input (i) = 500 J. Q2: Explain why scissors for cutting cloth may have blades longer than the handles but shears for cutting metals have short blades and long handles? Your email address will not be published. Our hand pushing an object or seesaws, crowbars. These types are based on the relative position of the fulcrum, load, and effort in the lever body. There are 3 types of lever depending upon the position of the fulcrum, the force and the weight: First Class, Second Class and Third Class Lever. Seesaw is an example of first class lever where the pivot(fulcrum) is in the middle.eval(ez_write_tag([[300,250],'physicsteacher_in-box-4','ezslot_4',150,'0','0'])); Other examples of class I lever: a pair of scissors, beam of physical balance, claw hammer, crowbar, pair of plierseval(ez_write_tag([[250,250],'physicsteacher_in-banner-1','ezslot_3',151,'0','0'])); What is the second class lever or class II lever? eval(ez_write_tag([[250,250],'physicsteacher_in-large-mobile-banner-1','ezslot_8',154,'0','0']));Other examples of class II lever: a bottle opener, a wheelbarrow, a bar used to lift a load. A first-class lever has the fulcrum (fixed point) between the input force and load.
While shears used for cutting metals have short blades and long handles because it enables us to overcome. These types of levers are First Class lever or class I lever, Second Class lever or class II lever, and Third Class lever or class III lever. The Fulcrum (pivot) is between the Load and the Effort such that, Length of Load Arm (La) = Length of Effort Arm (Ea).]. Did you notice that when you try to tear the paper into equal parts manually, it takes much time? Pulling a nail out of a wooden plank also represents a first-class lever. Pro, Vedantu Learn the various lever types in details at BYJU'S.
The lever is a rigid bar which basically allows a heavier or a steadfast object lying on the fixed point with a smaller force. eval(ez_write_tag([[250,250],'physicsteacher_in-medrectangle-3','ezslot_5',170,'0','0'])); The three types of levers are as follows: (1) First Class lever or class I lever, (2) Second Class lever or class II lever, and (3) Third Class lever or class III lever. He is an avid Blogger who writes a couple of blogs of different niches.
S.I.
In this case, we have to apply more energy to displace the weight to a longer distance. These are the levers in which the fulcrum is at one end and the force is applied in the middle and the weight is on the other end.
