A 200-kg machine is attached to the end of a cantilever beam of length L= 2.5 m, elastic modulus E= 200x109 N/m2

, and area moment of inertia I =

1.8x10–6 m4. Assuming the mass of the beam is small compared to the mass

of the machine, what is the stiffness of the beam?​

Hahahah jsu’s hsjshshsh. shjshshshsh.

The answer would be a

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
