The bracket abc can be supported in the eight different ways shown.
all connections consist of smooth pins, rollers, or short
links.
in each case, determine whether:
a) the bracket is over (redundant), completely, partially, or
improperly constrained
b) the reactions are statically determinate (sd) or statically
indeterminate (si)
c) the equilibrium of the bracket is maintained in the position
shown
also, wherever possible, compute the reactions, assuming that the
magnitude of the force p is 100 lb.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

What is creep? what is stress relaxation?
