Answer:
9064.44 Nm
Explanation:
Since the steel is uniform, the center of mass is also at the geometric center, which is 3.5 / 2 = 1.75 m from the bolted point.
Let g = 9.81 m/s2. The weight of the beam and the worker is
So the total torque about the bolted point is the sum of product of weights and distances from weight to the bolted point
Human building a drainage system could affect the water cycle because :
C. water would be directed to a new location because of the drains
This could potentially changed the natural occurrence that usually happened within the water cycle
hope this helps
Answer:
N = 3600 N
Explanation:
centripetal acceleration requirement is
ac = v²/r = 20²/50 = 8 m/s²
As the only available acceleration is gravity, centripetal acceleration must come from that,
This makes the "weight" that the road senses and must counteract
N = m(g - ac)
N = 2000(9.8 - 8)
N = 3600 N
