ANSWER

Why do we prefer a wrench with long arm to open ascrew

Posted by Ashutosh Kumar 7 years, 2 months ago

Amayra Singh 7 years, 2 months ago

This is the case of rotational motion so the torque is the applying force. And torque =F*r so by increasing radius of rotational motion we can increase torque and to increase radius we need a longer wrench. So longer wrench increases force (torque) and produce more turning effect and screw will easily open.

As one knows TORQUE = R cross F => F = torque/R As torque required to open a nut is constant. So F is inversely proportional to R. Hence if load arm is long we require less force to open.if there is any better ans let me know

Theorem of perpendicular axes:- The moment of inertia of a body (lamina) about an axis perpendicular to its plane is equal to the sum of its moments of inertia about two perpandicular axes concurrent with perpendicular axis and lying in the plane of the body. Theorem of parallel axes:- The momentof interia of a body about any axis is equal to the sum of the moment of inertia of the body about a parallel axis passing through its centre of mass and the product of its mass and the square of the distance between two parallel axes.

Why the bags are provided with broad handles

Posted by Dil Fariyad 7 years, 2 months ago

CBSE > Class 11 > Physics

1 answers

Priya Dharshini ☺☺ 7 years, 2 months ago

Bags should be provided with broad handles because it decreases the pressure by increasing surface area which makes it easier to carry them. On the other hand, thin straps decrease surface area which results in more pressure and it becomes hard for us to carry them.
