4. For each of the five L-shaped members shown, state whether the member is fully constrained\" or partially constrained.\" If a member is partially constrained, then you must briefly explain why it is considered partially constrained. NOTE that each roller shown is actually a \"roller ina confined smooth slot\" that can provide either a \"push\" or a \"pull\" (see textbook Table 5-1).] Ta) VIN ROLLER c) PIN D) KOLLR PIN ROLLE tl ROLLER RoLLER ROLUR ![4.

Solution
(a) It is fully constrained. because support reactions are present to resist any movement (along x, y or rotation)
(b) It is also fully constrained.
(c) It is partially constrained because left part is free to traslate vertically and thus it is free to rotate about right end pin.
(d) It is also partially constrained because left part is free to traslate vertically and thus it is free to rotate about right end pin.
(e) It is partially constrained because movement along horizontal axis is not restricted, so under the action of load P it will move towards left, so not stable.
