Concept explainers

Rotational Equilibrium And Rotational Dynamics

In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.

Equilibrium of Forces

The tension created on one body during push or pull is known as force.

A tightrope walker stands on a wire that is supported by a pole at each end. The tightrope walker creates a tension of 3.42 ✕ 103 N in a wire making an angle 6.2° below the horizontal with each supporting pole. Calculate how much this tension stretches the steel wire (in cm) if it was originally 16 m long and 0.50 cm in diameter. This question keeps getting rejected as incomplete. This is not incomplete. There is no image to accompany it. This is the entire question. PLEASE stop rejecting it. It is getting incredibly frustrating.

a. A 1200-N uniform boom of length 2.00 m is supported by a cable, as shown in the figure. The boom is pivoted at the bottom, and a 2000-N weight hands from its top. Find the tension in the cable and the components of the reaction force exerted on the boom by the floor. For the next two parts you can assume that the 2000-N weight is concentrated at the top end of the boom. b. Determine the total moment of inertia of the boom/weight system around the pivot point. c. The cable now breaks, and the boom pivots until the right end hits the floor. Determine the velocity of the right end at the instant before it hits the floor.

Back when I was a kid, I loved to play with my Hot Wheels. Hot Wheels are miniature metal cars that race down lengths of flexible track. The track comes in segments that can be connected together. One thing you can do is make the cars Loop the Loop, as shown in the figure above. Starting at a height, h, the cars race down the track, traverse a circular loop of radius, R, without falling down at the top of the loop, and then continue racing along a section of level track. If the loop is 9 inches in diameter, what is the minimum height, h, from which the cars can start and still loop the loop without falling down at the top? Neglect friction and air resistance.
