Question

State whether its true or false


1) A machine cannot change the direction of effort to a convenient direction.

2) The lesser the mechanical advantage of a machine,the smaller is the effort required for a certain load.

That's it

1.. true

2..false

Answer 2

Answer:

1st false 2nd true

Explanation:

Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. ... That's because a machine doesn't change the amount of work and work equals force times distance.

In an actual pulley due to friction, the mechanical advantage is less than 1 (i.e. the effort is more than the load). The reason for using the pulley when its mechanical advantage is equal to 1 or less than 1 is that the pulley allows us to apply the effort downwards i.e. in a convenient direction
