The maximum bending moment for a simply supported beam with a central point load is given by M = WL^2/8.

The maximum bending moment (M) for a simply supported beam with a point load (W) at the center and length (L) is given by M = WL/4.

The maximum bending moment (M) for a simply supported beam with a point load (W) at the center is given by M = WL/4, where L is the length of the beam.

The maximum deflection (δ) for a cantilever beam with a point load (P) at the free end is given by δ = PL^3/3EI.

The maximum grade recommended for a highway is typically around 5% for safety and comfort.

The maximum shear force occurs just to the left of the load, which is equal to the point load, hence it is 15 kN.

The maximum size of coarse aggregate used in concrete mix design is typically 20 mm, but can go up to 40 mm depending on the application.

The maximum size of coarse aggregate used in concrete is typically 20 mm to 40 mm, depending on the application.

AASHTO guidelines recommend a minimum horizontal curve radius of 100 m for a design speed of 60 km/h.

For a design speed of 60 mph, a minimum horizontal curve radius of 500 feet is typically recommended to ensure safety.

The minimum stopping sight distance for a design speed of 60 mph is typically around 300 feet.

The moment of inertia (I) for a rectangular beam section is given by I = (b * h^3) / 12, where b is the width and h is the height of the section.

Flexible pavement typically has a lower initial cost compared to rigid pavement, making it a more economical choice for many applications.

High-strength steel allows for reduced weight of structures, leading to more efficient designs.

Lightweight aggregates reduce the weight of concrete, making it suitable for applications where weight is a concern.

The primary advantage of using the stiffness method is its ability to handle indeterminate structures effectively.

The primary advantage of using the virtual work method is its applicability to indeterminate structures, allowing for the calculation of deflections and internal forces.

The primary advantage of using trusses in construction is lower material usage while maintaining structural integrity.

The primary assumption made in the Euler-Bernoulli beam theory is that plane sections remain plane after deformation, along with the material being isotropic and elastic.

Flexible pavement materials provide better load distribution, allowing them to adapt to traffic loads and environmental conditions.

Flexible pavement typically has a lower initial cost compared to rigid pavement, making it a more economical choice for many projects.

High-performance concrete offers higher durability and strength, making it suitable for demanding applications.

Lightweight aggregates reduce the overall density of concrete, which can lead to increased compressive strength and improved thermal insulation properties.

Using recycled materials in pavement construction can significantly lower costs while also being environmentally friendly.

Traffic calming measures are primarily implemented to enhance pedestrian safety by reducing vehicle speeds in residential areas.

Liquefaction is the primary cause of bearing capacity failure in sandy soils during seismic events, as it can lead to a sudden loss of strength.

In saturated soils, increased pore water pressure reduces effective stress, leading to bearing capacity failure.

Differential settlement is primarily caused by soil heterogeneity, where different soil layers compress at different rates under load.

Secondary compression occurs due to the rearrangement of soil particles over time, even after primary consolidation has been completed.

Settlement in saturated clay soils primarily occurs due to consolidation, which is the process of volume reduction in soil due to the expulsion of water from the pores under applied loads.
