Let the left end A and the right end B.
Let w = the weight of the full beam.
0 = -(w/2)*(L/4) - (w)*(L/2) + Fa*L
Fa = [(w/2)*(L/4) + (w)*(L/2)]/L = w/8 + w/2 = 5/8*w = 5/8*m*g = 5/8*1800*9.81 Fa = 11036.25 N
Fa + Fb = w Fb = w - Fa = 1.8*(1800*9.81) - 11036.25 Fb = 20748.15 N
Answer:
13 u2 = 0 – (2 × –2 m/s2 × 6 m) = 24, u = 4.9 m
Explanation:
Answer:
Friction = 5.027 N
Explanation:
Kinetic friction does not change with speed or acceleration. The only thing that is required is to state that the object is moving.
Solving the force equation for friction we get:
Friction = coefficient of friction* normal force exerted by the object
Friction = u * R
here R is = 0.84 * Gravity = 0.84 * 9.81 = 8.2404 N
u = 0.61 (as stated in the question)
So frictional force will be:
Friction = 0.61 * 8.2404
Friction = 5.027 N
Heat pumps are also known as refrigeration units for heating and cooling homes by taking heat from air outside in the winter time and then reversed to take heat out of the inside of a home in the summertime. The Geothermal heat pumps take heat from the ground by way of buried pipes deep in ground with chemicals such as water and glycol or similar and transfers that heat into homes in the winter time.
