A beam supported at both ends and at an intermediate support is acontinuous (statically indeterminate) beam. Under uniform loading, continuity over the interior support createsnegative bending moment (hogging)at the middle support and redistributes shear and reactions compared with a simply supported span.
Standard structural analysis references note that continuous beams are statically indeterminate and are analyzed using methods such as thethree-moment equationto determine reactions and internal moments. For symmetric geometry and uniform load, the interior support typically attracts a larger share of the reaction because continuity restrains rotation and increases load transfer to the middle support. The end supports still carry reaction, but the redistribution generally results in themiddle reaction being greater than either end reactionfor the common case oh an intermediate support under uniform load. Thus, the correct statement is that the reactions aregreater in the middle than at the ends.

When inspection identifies nonconforming work relative to IFC drawings, the inspector/technologist's role is todocumentthe condition (location, description, measurements, photos) andnotify the responsible design professional/engineerfor disposition. This aligns with formal quality control/assurance processes: field staff identify and record deviations; the engineer evaluates structural implications and issues written instructions (accept as-is, remediate, redesign, or replace). Acting unilaterally to remove a beam (option B) exceeds typical authority and may create safety and contractual issues. Simply filing without notification (C) fails to address a potentially serious structural deficiency. Rechecking the IFC calculations (D) is not the immediate construction control action; the priority is to initiate an engineering review of the nonconformance. Civil engineering project practice stresses maintaining complete inspection records and communicating significant issues through appropriate channels for corrective action. Therefore, the correct action isdocument the issue and notify the engineer.

For vertical curves, AASHTO uses theK valuedefined as, whereis curve length (m) andis the algebraic difference in grades (percent). Here,and, so. Withstopping sight distance controlled by the same criterion(i.
e., the applicable K value for the given design speed remains the same), length is found from. For 90 km/h, the SSD-based K for the controlling curve type yieldsthat corresponds to60 mforper the provided choices.
This reflects standard vertical-curve practice: once K is set by SSD for the design speed, length scales linearly with the grade difference.

Concrete cylinder samples must represent thedelivered batch, so sampling must avoid the non-representative portions at the beginning and end of discharge where segregation and water/aggregate distribution can differ.
ASTM C172/C172M sampling practice requires collecting acomposite samplefrom themiddle portionof the load: specifically, not before about10%and not after about90%of the batch has been discharged, using two or more portions taken at regularly spaced intervals. A paper hosted by ASTM discussing sampling from truck mixers references ASTM C172/C172M and its requirement for collecting multiple portions from the discharged batch. Training/field guidance consistent with ASTM C172 also states sampling should occur after
~10% and before ~90% of discharge (i.e., the middle of the load). Therefore, the correct answer isin the middle of the load (Option C).

For an axially loaded pile in compression, the resisting capacity comes from two primary components:end bearing at the tipandskin friction along the shaft. These components act together, and total pile resistance is typically expressed as thesumof tip resistance and shaft resistance. In standard geotechnical capacity formulation, the ultimate pile capacity is written as, whereis the shaft (friction) capacity andis the point (tip) capacity. Lindeburg's deep foundation section similarly explains that point-bearing and skin-friction capacities are simultaneously present to some degree in piles, and total support is based on their combined contribution. In the diagram,represents the tip component (unit tip resistance times tip area) andrepresents shaft resistance. Thereforecannot exceed the combined available resistance and is properly described asless than or equal to.
