Physics & mechanics
Free-body diagrams belong on site and in a classroom. We do not replace that.
Study notes. Not a certificate. Not a licence. Not NEBOSH, PESO, ISEE, or IDE. We never design the charge, spacing, or the cut. Site hours and statutory papers have no video substitute.
Newtonian mechanics, free-body diagrams, equilibrium.
