In beams what is a zero bar?
A zero bar is a bar in a truss that supports no load but is only there for the stability of the structure
How do you Convert Torque Nm to Force N?
Torque T=Nmsin x, thus Force N=T/msin x. If sin x is zero Torque is zero and Force is zero.
Withdrawel force of steel nails?
In engineering, the code-allowable withdrawel force is zero, because the wood expands and contracts over time and the nail pull-out force can reduce to zero.
Is the acceleration of a simple harmonic oscillator ever zero if so where?
Yes; the acceleration is zero when the velocity is at its maximum, that is, at the equilibrium position. Since the force and hence the acceleration always act TOWARDS the equilibrium position (because it's a restorative force), then the force and acceleration must change their sign as the mass crosses the e.p., and therefore must be zero instantaneously at the e.p.
What do you mean bu equivalent shear force and equivalent bending moment?
MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
