I think this one's B. energy and work are both measured in joules.
Answer:
Explanation:
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces.
Given:
Uniform distributed load with an intensity of W = 50 kN / m on an overhang beam.
We need to determine the maximum shear stress developed in the beam:
τ = F/A
Assuming the area of the beam is 100 m^2 with a length of 10 m.
τ = F/A
τ = W/l
τ = 50kN/m / 10 m
τ = 5kN/m^2
τ = 5000 N/ m^2<span />
From the law of conservation of momentum
m1u1+ m2u2= m1v1+ m2v2
110*8+ 110*-10= 110*-10 + 110* v2
v2= 8 m/sec
Gravity affects weight of an object
Its weight reduces as it moves away from the center as gravity is strongest near the core and reduces as you move away
Hope this helps C:
