The board weighs 60 N and is 3.0 m long. What is the magnitude of the normal force of the left stand acting on the beam, in Newtons? (Hint: Clearly draw a diagram with the pivot, forces, and r associated with each force.) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 3.0 m 1.0 m

Can somebody help please
The board weighs 60 N and is 3.0 m long. What is the magnitude of the normal force of the left stand
acting on the beam, in Newtons? (Hint: Clearly draw a diagram with the pivot, forces, and r associated
with each force.)
Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not
include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the
question statement.

A uniform beam weighing 10 N sits at rest across two triangular stands. The beam has a length of 1.0
m. Assume the left end of the beam is at origin, the left stand is at position 0.10 m and the right stand is
at position 0.80 m. What is the magnitude of the normal force of the left stand acting on the beam, in
Newtons? (Hint: Clearly draw a diagram with the pivot, forces, and r associated with each force.)
Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not
include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the
