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.

Chapter 12, Problem 18P

GO In Fig. 12-35, horizontal scaffold 2, with uniform mass m₂ = 30.0 kg and length L₂= 2.00 m, hangs from horizontal scaffold 1, with uniform mass m₁ = 50.0 kg. A 20.0 kg box of nails lies on scaffold 2, centered at distance d = 0.500 m from the left end. What is the tension T in the cable indicated?

a vertical uniform beam of length Lthat is hinged at its lower end.A horizontal force F is applied to the beam at distance y from the lower end. The beam remainsvertical because of a cable attached at the upper end, at angle uwith the horizontal. gives the tension T in the cableas a function of the position of the applied force given as a fractiony/L of the beam length.The scale of the T axis is set by Ts= 600 N.Figure 12-49c gives the magnitude Fh of the horizontal force on thebeam from the hinge, also as a function of y/L. Evaluate (a) angle uand (b) the magnitude of .

Questions 15-19 A rod of length L with non-uniform mass distribution is hinged horizontally to a vertical wall from one end. The rod is supported by a rope from the other end as shown in the figure such that the rope makes an angle of 30° with the horizontal. The linear mass density (mass per unit of length) of the rod is A(x)=8Cx/L where x is the distance from the hinge (x < L) and C is a constant. The unit of C is kg. The distance between point mass m and the hinge is L/2. M 15. What is mass M of the rode? (а) 8C/3 (Ь) 2C (е) С/2 (а) С (е) 2C/3

One end of a uniform ℓ = 4.40-m-long rod of weight w is supported by a cable at an angle of ? = 37° with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod is ?s = 0.570. Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A._______________________ m
