Why do tightrope walkers use a pole?

A wire-walker may use a pole for balance or may stretch out his arms perpendicular to his trunk in the manner of a pole. This technique provides several advantages. It distributes mass away from the pivot point, thereby increasing the moment of inertia.

Can a small force ever exert a greater torque?

ANSWER: Yes, a small force can exert a greater torque than a large force. Torque equals the product of the force and the lever arm distance. Therefore, if the lever arm distance is large enough, the torque exerted by the small force will be greater than that exerted by a large force with a small lever arm distance.

Why do tightrope walkers Fig 8 34 carry a long narrow rod?

Why do tightrope walkers carry a long, narrow beam? The long beam increases the rotational inertia of the walker. With a larger rotational inertia, the angular acceleration caused by that gravitational torque will be smaller, and the walker will therefore have more time to compensate.

Can the diver do a somersault?

The diver can indeed accomplish a somersault without having any initial rotation while leaving the board. Due to the law of conservation of angular momentum, moment of Inertia is greater as the body is stretched with a reduced angular velocity.

Why do divers tuck?

The tuck position carries the lowest tariff of all the diving positions. It is the easiest dive position to get into and the fastest in which to perform somersaults. This means the diver can kick out for entry sooner, or fit more somersaults into their dive….

Why is water sprayed into a diving pool?

Diving competitions usually have water spraying on the pool while divers dive because: A. it reduces the surface tension through turbulent flow and reduces the amount of force absorbed by the diver. B. it reduces the glare on the pool surface allowing divers to better see their target at the bottom of the pool.

What is the record for longest free dive?

Freediving – no limit (men) The deepest no-limit freedive by a male is 214 m (702 ft 1.18 in), by Herbert Nitsch (Austria) in…
