2.8 Two Dimensional Applied Forces Review

True or False: Normal Force is ALWAYS equal to the weight.

• True

• False

Answer explanation

This is only true for flat surfaces where the applied angle is in the x direction (horizontal).

What is the x component of a 50 N applied force at 35 degrees from the horizontal? (Round to whole number).

What is the y component of a 50 N applied force at 35 degrees from the horizontal? (Round to whole number).

What is the x component of a 12.5 N applied force at 40 degrees from the horizontal? (Round to whole number).

What is the y component of a 12.5 N applied force at 40 degrees from the horizontal? (Round to whole number).
