Explanation

• The joints of a truss should ideally experience purely concentrated point loads.
• In an ideal truss, loads are assumed to act at the joints (nodes).
• Truss members are subjected mainly to axial tension or compression

Explanation

• The command used in AutoCAD to make round edges is the Fillet command
• Shortcut: F → Enter.
• It creates a curved connection with a specified radius.
• It is commonly used for rounding the corners of lines, arcs, polylines, and other objects.

Explanation

• AutoCAD Civil 3D is widely used for road and highway geometric design.
• It can create horizontal and vertical alignments.

Explanation

• A brick is considered weak if it absorbs more water
• More pores: High water absorption shows the brick has too many empty spaces inside.
• Less strength: These empty spaces make the brick weak and unable to hold heavy weight.

Additional information

• Good quality bricks should have low water absorption, typically less than 20% of their dry weight.

Explanation

For a simply supported beam carrying a UDL over the entire span:

• The maximum bending moment occurs at the center of the span.
• Formula: Mmax = wL^2/8​
• w = uniformly distributed load per unit length.
• L = span of the beam.
