What is hooks law.? |
| Answer» Hook’s Law=According to this Law, the force needed to change the shape of spring is proportional to the displacement of the spring. The displacement referred here is how far the spring is compressed or stretched from its normal shape. Mathematically, Hook’s Law can be summarised as F= – k x.<br>Strain is directly proportional to stress | |

Impulse momentum theorem derivation |
| Answer» The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it. The impulse-momentum theorem is logically equivalent to Newton\'s second law of motion (the force law). Search in google for derivation since it cannot be typed here | |

Difference between torque and force and all the best for u r exams |
| Answer» Ur wlcm<br>Thanks niraj ji<br>Thanks priya ji<br>When you apply force in qual and opposite on any object, it gets converted into torque.Torque is the rotating force , torque is the product of force and center to point of force distance , while force is the product of mass and acceleration. Hope u get the difference<br>When you apply force in couple (equal and opposite)on any object, it gets converted into torque. Torque is the rotating force , torque is the product of force and center to point of force distance , while force is the product of mass and acceleration. | |

Is break down of helmet is boon or ban for human safety during accidents?Why? |
| Answer» It is curse because if our neck is weakest point and for sure we will get hurt. Because of third law of motion<br>Hey Priya Dharshini..Thank you...But sorrry for this,can you you explain it in simple language..<br>When you apply force in couple (equal and opposite)on any object, it gets converted into torque. ... Torque is the rotating force , torque is the product of force and center to point of force distance , while force is the product of mass and accelerationThat, in and of itself, will decrease the amount of force necessary to break a neck. In other words, if the body and head are not in line head is at 45 degrees to the body; force of impact is a constant; and as we all know, the neck is the weakest part of the body; the amount of applied force needed to severe the spinal column will be much less. That, my friends, is the reaction of Newton\'s third law of motion.For every action, there is an equal and opposite reaction. What that means is the applied force (i.e., 600, 780 or 900) will be dissipated. How force is dissipated doesn\'t matter, but it will be dissipated. In a bike wreck, the applied force could very well be dissipated through youThat, in and of itself, will decrease the amount of force necessary to break a neck.

Why do we prefer a wrench with long arm to open ascrew |
| Answer» 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.<br>As one knowsTORQUE = R cross F=> F = torque/RAs 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<br>Eisjsj the c chij tu UC fb | |

Why the bags are provided with broad handles |
| Answer» 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. | |
