1- Three forces act on a point: 3 N at 0°, 4 N at 90°,and 5 N at 217°.
a. What is the net force? b. What fourth force will putthe point in equilibrium?
2- A 100 kg wooden crate rests on a wooden ramp with anadjustable angle of
inclination.
a. Draw a free body diagram of the crate. b. If theangle of the ramp is set to 10°, determine...
i. the component of the crate's weight that isperpendicular to the
ramp ii. the component of the crate's weight that isparallel to the ramp iii. the normal force between the crate andthe ramp iv. the static friction force between the crate and theramp
v. At what angle will the crate just begin toslip?
