What else can I help you with?
Can a force produce a torque when there is no lever arm?
no because to get a torque you must multiply lever arm by force. If lever is zero, then torque is zero
Can a body be in equilibrium if it is revolving clockwise under the action of single torque?
No, a body cannot be in equilibrium while revolving clockwise under the action of a single torque. In order to be in equilibrium, the net torque acting on the body must be zero, which is not the case when a single torque is causing the body to rotate.
Can an obeject be in equilibrium if the only torques acting on it produce clickwise rotation?
No, for an object to be in equilibrium, the net torque acting on it must be zero. If all torques are producing clockwise rotation, there will be a net torque causing the object to rotate in that direction, not in equilibrium.
What is mean sum of all torque on the object must be zero in cindition of equilibrrium?
In a condition of equilibrium, the sum of all torques acting on an object must be zero because torque is responsible for rotation. If the total torque is not balanced (i.e., not zero), the object will start rotating. By ensuring that the sum of all torques is zero, we guarantee that the object stays in a stable, balanced position without any rotational movement.
What is the condition of its being the dynamic balanced called?
The condition for a system to be dynamically balanced is that the sum of the moments (forces multiplied by their distances) acting on the system must be zero. This means that the system is in rotational equilibrium, with no net torque acting on it.
How do clockwise and counterclockwise torques compare in a balance system?
In a balanced system, the clockwise and counterclockwise torques are equal in magnitude but opposite in direction. This equilibrium condition ensures that the net torque around the pivot point is zero, allowing the system to remain stable and not rotate. If one torque exceeds the other, the balance will tip in the direction of the greater torque. Thus, for balance, the two torques must be perfectly balanced.
Can a force produce a torque when there is no lever arm?
no because to get a torque you must multiply lever arm by force. If lever is zero, then torque is zero
Where would place a fulcrum of a lever if you had to lify a heavy load?
A fulcrum would be placed as close to the heavy load as possible. This minimizes the lever arm (and thus minimizes the torque) for the load while maximizing the lever arm (and thus maximizing the torque) for the force you must apply.
Can a body be in equilibrium if it is revolving clockwise under the action of single torque?
No, a body cannot be in equilibrium while revolving clockwise under the action of a single torque. In order to be in equilibrium, the net torque acting on the body must be zero, which is not the case when a single torque is causing the body to rotate.
What is lever balance?
Lever balance refers to a system used to measure weight or mass by balancing an object against known weights on a lever arm. The lever operates on the principle of moments, where the torque produced by the weights on one side of the fulcrum must equal the torque produced by the object on the other side for balance to be achieved. This mechanism allows for precise measurements in various applications, from scientific experiments to weighing goods. Lever balances are often favored for their accuracy and simplicity compared to electronic scales.
Can an obeject be in equilibrium if the only torques acting on it produce clickwise rotation?
No, for an object to be in equilibrium, the net torque acting on it must be zero. If all torques are producing clockwise rotation, there will be a net torque causing the object to rotate in that direction, not in equilibrium.
What is mean sum of all torque on the object must be zero in cindition of equilibrrium?
In a condition of equilibrium, the sum of all torques acting on an object must be zero because torque is responsible for rotation. If the total torque is not balanced (i.e., not zero), the object will start rotating. By ensuring that the sum of all torques is zero, we guarantee that the object stays in a stable, balanced position without any rotational movement.
Is it possible for forces acting on a given body to balanced each other and still rotate due to these balanced forces?
Yes. For the object not to move, two conditions must be satisfied: (1) The vector sum of forces must be zero, and (2) The vector sum of torques must be zero. Do some reading on torque, for more information.
What is the effect of torque on airplanes?
On prop driven aircraft the torque created by the engine, along with other forces, creates a left turning tendency. The pilot must compensate for this by adding right rudder. Keep in mind that on US prop built aircraft the prop turns clockwise (as seen from the cockpit) and the prop torque is as stated above. However, on many European designed aircraft, the prop turns counter clockwise and therefore, the prop torque produces a right turning tendency.
What is the condition of its being the dynamic balanced called?
The condition for a system to be dynamically balanced is that the sum of the moments (forces multiplied by their distances) acting on the system must be zero. This means that the system is in rotational equilibrium, with no net torque acting on it.
How far out from an axis must a 1200 N force be applied in order to counter and hold a 90 Nm torque acting in the clockwise direction?
90 / 1200 meter, or 0.075 of a meter.
What conditions must be met for an object to be at equilibrium?
For an object to be at equilibrium, the net force acting on it must be zero, which means that the forces are balanced and cancel each other out. Additionally, the object must not be accelerating, so the net torque acting on it must also be zero.
