The shear shown is used to cut and trim electronic circuit board laminates. For the position shown, determine (a) the vertical component of the force exerted on the shearing blade at D, (b) the reaction at C.

ENGR 121 B Lab Notes for 9/28/2016 Spencer Kociba ● vec=a:b:c ○ a=min/starting number ○ b=increment ○ c=max number ● logspace(X1, X2, N) ○ X1=starting point is 10^X1 ○ X2= ending point is 10^X2 ○ N= number of elements created ● x=([a:b], c) ○ a=start ○ b=end ○ c=the last element of the vector ○ Ex. mat=([5:1:3]; 1:3; 44, 9, 2) ■ >>> ● numel(matrix name) ○ Counts number of elements in the specified matrix/vector ● x=mat(3:)
