1. The steepest angle at which a sloping surface formed of a particular loose material is stable.  It varies locally according to the mechanics and strength. 

• Angle of repose  

• Angle of friction

• Acute angle

• 300 angle

It is the SI unit of a force required to give a mass of 1 kg an acceleration of 1 m/s2 and is equivalent to 100,000 dynes

• Pascal or Pa

• Load

• Mass

• Newton or N

  
  

It is the strength of the structure that resists the external applied forces. It is also the pressure or tension exerted on a material object. NSCP defines it as force per unit area

• Hardness

• Durability

• Stress

• Rigidity

What stress is developed when the force applied tends to shorten the structure

• Axial

• Shear

• Compressive

• Flexural

A hinge support has two reaction components for 2 dimensional axis; how may reaction components for 3-dimensional axis.

• 1

• 2

• 3

• 4

The distance between two structural supports of a roof truss is called span length. What do you call the spacing between trusses

• Effective length

• clear distance

• Span Length

• Bay length

Why is it the long-spanned trusses are cambered

• For longer life span

• Aesthetics design to look good

• To minimize or prevent deflection

• NSCP requirement

These structure are generally compressed, as such, they are considered "compression members"

• Truss members

• Beams

• Columns

• Footings

The angle between the total reaction and the normal force when limiting friction is acting is called?

• angle of friction

• Angle of repose

• Angle of contact

• Coefficient of friction

1. Newton (N) is the SI unit of Force and was named after Isaac Newton in recognition of his contributions to the field of Mechanics. It is denoted by N and is expressed in 

• kg. m2/s2

• kg.m/s2

• kg.m/s

•  kg.m2/s
