A machine whose mechanical advantage is 3,lifts a load of 30 N.What effort is applied to the machine
To determine the effort applied to the machine, we need to use the concept of mechanical advantage.
Mechanical advantage is defined as the ratio of the force output of a machine to the force input. It gives us an idea of how much the machine multiplies the input force.
In this case, the mechanical advantage is given as 3. This means that for every 1 unit of force applied to the machine (effort), it can produce 3 units of force (load).
To find the effort, we can set up the equation:
Mechanical Advantage = Load / Effort
Plugging in the given values, we have:
3 = 30 N / Effort
To solve for Effort, we can rearrange the equation:
Effort = Load / Mechanical Advantage
Effort = 30 N / 3
Effort = 10 N
Therefore, an effort of 10 Newtons is applied to the machine.
