A woman holds a 1.90-m-long uniform 5.0-kg pole as shown in (Figure 1) ( its horizontal).

Question

A. Determine the force she must exert on the pole at A.
Express your answer to two significant figures and include the appropriate units. Enter positive value if the force is upward and negative value if the force is downward.

B. Determine the force she must exert on the pole at B.
Express your answer to two significant figures and include the appropriate units. Enter positive value if the force is upward and negative value if the force is downward.

C.To what position (B′) should she move her left hand so that neither hand has to exert a force greater than 80 N ?
Express your answer to two significant figures and include the appropriate units.

D. To what position (B′′) should she move her left hand so that neither hand has to exert a force greater than 40 N ?
Express your answer to two significant figures and include the appropriate units.

Please help my professor barely taught static equilibrium......

Answer 1

where these points are or why she is exerting 80 N on a pole that weighs about 50 N Is she holding it near and end - up with one hand and down with the other to balance weight and moments?

Answer 2

google search the first part of the equations i have it up with the picture
