Question

Problem 9. Eight identical rectangular plates each weighting W 3.2 kN are held in a vertical plane as shown. All supports consist of frictionless pins, rollers, or short links. In each case, draw in the reactions of the supports, and indicate by circling the appropriate choices below whether the plate is completely, partially, or improperly constrained, whether the reactions are statically determinate or indeterminate, and whether the system is in or out of equilibrium under the given loading conditions. (a) completely constrained (b) partially coestrained (c) improperly constrained (d) statically delerminate (e) statically indeterminate (a) completely coustrained (b) partially coustrained (c) improperly coustrainesd (d) statically delerminate (e) statically indeterminae ( in equilibim (g) out of equibbi B (D in equailitbrium (g) out of equilibrim (a) completely constrained (b) partially constrained (c) improperly constrained () statically delerminate (e) statically indetermminale (a) completely constrained (b) partially constrained (c) improperly coustrained () statically deverminate (e) statically indetermminale (0 in equalibim (g) out of equiibuin 3 (g) out of egalibriim (a) completely constrained (b) partially coustrained (c) improperly constrainesd (d) statically determinate (e) statically indetermminae (0) in equailibrim ) out of equalibi (a) completely constrained (b) partially constrained (c) improperly coustrainesd (d) statically deserminate (e) statically indetermine () in equilibm (g) Out of equltrwun 6 (a) completdly constrained (b) partially coustrained (c) improperty constrained d) statically determinate (e) statically indeterminate () in equilibrium (g) out of equilibriim (a) completdly constrained (b) partially coustrained (c) improperly constrained (d) statically determinate (e) statically indeterminate ( in equiliim (g) out of equilibrin
