He deflections (you will need to define a non-dimensional number  = EI/kL3 characterizing the stiffness of the spring) for various values of the spring stiffness. Plot also the variation of the deflection of the end of the beam (x=L) as a function of  Comment on your results (for example what happens when the spring becomes stiff? What happens when k tends to zero?). Finally, plot (in a non-dimensional way) the moment distribution along the beam. Find the expression of the axial stress along the bottom side of the beam, assuming that the cross section is rectangular and is defined by - a / 2 £ y £ a / 2 ; -b /2 £ z £ b/s.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

false

hope this : d
