How many forces are acting on the 10 kg box? Select all that apply

• weight (w)

• Normal force (Fn)

• Tension 1 (T1)

• Tension 2 (T2)

This free body diagram represents all the forces acting on a hanging object ( without x and y components)

This free body diagram represents the x and y components of both tensions and weight

A cable with a tension of 850 N at 60° will have a y-component equal to:

• 425 N

• -38.56 N

• 736.12 N

• 45.96 N

Calculate the x-component of a force equal to 25 N at 20°

• 8.55 N

• 23.49 N

• 8.45 N

• 18.12 N

Look at the free body diagram, how would you write "Forces right=forces left"

• $T_{1x}=T_{2x}$

• $T_{1y}+T_{2y}=W$
