Frank Modern Certificate Solution for Class 10 Physics Chapter Unit - 1 - Force, Work, Energy and Power - Simple Machines Page/Excercise 38

Solution 1

A fixed pulley is used to change the direction of effort to a convenient direction.

Solution 2

A machine whose efficiency is 100% is referred to as an ideal machine.

Solution 3

Solution 4

No, a machine cannot be 100% efficient because mechanical advantage is always less than theoretical mechanical advantage due to friction and the weight of the moving parts.

Solution 5

Solution 6

The purpose of a machine is:
(i) To multiply force
(ii) To obtain a gain or decrease in speed
(iii) To change to direction of application of force in a convenient direction

Solution 7

(i) A jack is used to multiply force.
(ii) A lever is used to change the point of application of force.
(iii) A pulley is used to change the direction of application of force.
(iii) Gears are used to multiply speed.

Solution 8

Solution 9

A block and tackle system of pulleys consists of two blocks of pulleys, each block having one or more than one pulley. The upper block of pulleys is fixed to a rigid support and the lower block of pulleys is movable. The number of pulleys in the movable block is either equal to or one less than the number of pulleys in the fixed block.

Solution 10

When a single pulley is used with a mechanical advantage greater than 1, the effort has to be applied in the upward direction.

Solution 11

In a single fixed pulley, if the effort moves by a distance 'y' downwards, the load moves by a distance 'y' upwards because the velocity ratio of a single fixed pulley is 1.

Solution 12

A pulley whose axis of rotation is not fixed in position or space is called a movable pulley. Ideally, its M.A. is 2.

Solution 13

Solution 14

Solution 15

(a) A jack is used to multiply force.
(b) Gears are used to multiply speed.
(c) A pulley is used to change the direction of application of force.

Solution 16

Two uses of pulley:
(i) To change the direction of application of force to a convenient direction.
(ii) To multiply force.
Yes, a pulley is a force multiplier

Solution 17

Solution 18

Solution 19

A block and tackle system of pulleys consists of two blocks of pulleys, each block having one or more than one pulley. The upper block of pulleys is fixed to a rigid support and the lower block of pulleys is movable. The number of pulleys in the movable block is either equal to or one less than the number of pulleys in the fixed block.

Solution 20

Solution 21

(i) 'Gear ratio' is defined as the ratio between the number of teeth in the driven gear and those on the driving gear.
(ii) A vehicle moving uphill uses a lower gear to increase the torque and to raise velocity ratio i.e., speed decreased.
(iii) Gear ratio, in bicycle is less than one, thus, one rotation of 'penion' causes a number of rotations of 'idler'.
