Amass of 150 kg is supported at the end of a cantilever beam of length 0.8m. the modelus of elasticity of the beam is: e-210 x 109 n/m2 and second moment of area of the natural frequency of the system?

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

e) none of the above answers are correct

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
