Forces: Equilibrium Examples
2 Dimensional Equilibrium! Calculate force of hand to keep a book sliding at constant speed (i.e. a = 0), if the mass of the book is 1 Kg, m s =.84 and m k =.75 We do exactly the same thing as before, except in both x and y directions! Step 1 – Draw! Step 2 – Forces! Step 3 – Newton’s 2nd (F Net = ma)! Treat x and y independently ...
