"Can a system at equilibrium do work?"

Relativistic effects take place in the small, ie v c. If an object
is accelerated, it gains mass that way because of relativistic tradeoff
of velocity for mass to prevent it from achieving c, light speed.

So, does not a gyroscope under acceleration gain mass, even very, very
small amounts?

It gains an equivalent mass.
IOW a wreck involving a fast heavy vehicle
can make the same ammount of schrapnel as
a wreck of a slow lightweight vehicle
carrying a fast gyro.

When a particle splashs into a bucket of
water (calorimeter) and raises the temperature
we frequently don't know if the particle
was heavy, hasty or hot. )

I don't know how many volts I weigh on
a bathroom scale but an electon should
weigh 0.511MeV.

I don't understand that very well: as a massy object approaches c,
force applied does not increase the velocity delta F = m delta v,
instead it increases mass and velocity, delta F = delta m delta v. As
v approaches c, delta F = delta m v. At even small values of v the
coefficient of m is not unity. How do you talk about the tradeoff
between those two, mass and velocity, relativistically?
