why is a longer handle of the hammer and throwbar more advantageous?

Question

ita a conceptual question of torque..

Answer 1

Basically,

Torque = force * distance from pivot point to where force is applied

So to increase torque, you can either increase the force or go further from the pivot point (i.e where it moves about) It would be much easier to increase the distance than increase the force.

Answer 2

For an object to rotate about a point, the summation of the moments about that point cannot equal zero. In other words, if you take all the forces and multiply them by the distance they are from the point of rotation, the addition of all that will be the direction the object rotates. So to increase the rotation, you can increase the force or increase the distance from the point of rotation. The whole point is to be lazy and reduce the force required, so we increase the distance i.e. the handle.

Here is an easy example. Open hinged door normally and notice how hard you have to push on the door to open it. Now try opening the door by pushing right next to the hinges.

Also, by increasing the length of the handle on the hammer, we increase the angular momentum it has during the swing, which imparts more force onto the nail which is require to resist that moment.

Answer 3

This is due to the torque produced. Torque is a force applied so as to cause an angular acceleration.

The formulae for Torque,
τ = rF, where τ is Torque, r is the radius of your throwbar, and F as your applied force.

From this formulae, we can say that torque is proportional to the radius and applied force. The more the radius or applied force, the more Torque is produced. And thus, more angular acceleration is produced, the throwbar works more efficient.

Hope I did answer your question.

Answer 4

its the principle of leverage .. the longer the arm the larger the force applied because
torque= force * perpendicular distance..
this shows that the head of the hammer can be of optimum weight and when the length of the hammer increases then the amount of effort required is less.. there by less man power and work..

Answer 5

Because of the fulcrum effect! The longer the the handle the more torque you have

Answer 6

It gives the head more weight. You probably know as much as I do but I thought I had something there for a minute but I couldn't explain it. Sorry.

Answer 7

more torque because of the increase in moment arm, more leverage.

Answer 8

Leverage!

Answer 9

the longer the handle the more tourque you have

Answer 10

More leverage.
