Your new designer chair has an S-shaped tubular metal frame that behaves just like a spring with the spring constant 14000 N/m. When your friend, who weighs 940 N, sits on the chair, how far does it bend?

WE know that F = k x

where k : Spring constant = 14000 N/m

F = 940 N

therefore , x = F/k  = 940 /14000 = 0.0671 m    or 6.71 cm
