(I) A sign (mass 1700 kg) hangs from the bottom end of avertical steel girder with a cross-sectional area of 0.012 m2(a) What is the stress within the girder? (b) What is thestrain on the girder? (c) If the girder is 9.50 m long, howmuch is it lengthened? (Ignore the mass of the girder itself.)
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.
(I) A sign (mass 1700 kg) hangs from the bottom end of a
vertical steel girder with a cross-sectional area of 0.012 m2
(a) What is the stress within the girder? (b) What is the
strain on the girder? (c) If the girder is 9.50 m long, how
much is it lengthened? (Ignore the mass of the girder itself.)
