Class 5 Science Simple Machines Complete Chapter Youtube Class 5 science simple machines (complete chapter). learn what is simple machine and types of simple machine like lever, inclined plane, screw, wedge, wheel. A lever is a simple machine consisting of a rigid rod which is capable of turning around a pivot called a fulcrum. it has three parts, namely, effort, load and fulcrum. fulcrum: the rod of the lever rests on it and the lever rotates about it. load: the weight lifted by the liver is called the load. effort: the force applied on the other end of.
Simple Machines Chapter Science Class 5 Icse Cbse Board Exercise 2. machine answer: machines are simple devices or tools that make our work easier, faster and better. they reduce our efforts and save time in completing a work. machines can be simple or complex. 3. pulley answer: a pulley is a wheel with a grooved rim with a rope that can be used to lift heavy loads. 4. fulcrum. Pulley. a) a pulley is a grooved wheel with a rope or cable running along the groove. b) it helps us lift or lower objects easily by pulling on the rope. c) it can be fixed or movable. d) a fixed pulley changes only the direction of the force, while a movable pulley allows you to multiply the force applied.

There are six simple machines devised by human – levers, wheel and axle, pulleys, inclined planes, screws and wedges. the simple machines require human energy in order to work. a machine makes our work easier implies that we need less force to do the same amount of work. (b) a hammer works as class 1 and class 3 lever. answer: the lever class of a hammer depends upon its use. if the hammer is used as a claw to remove a nail, it is a first class lever. when the hammer is used to strike a nail, it is a third class lever. (c) the roads are inclined and go round and round on hills.
