EXAC Exam Questions with Accurate Solutions
Static Load vs Dynamic Load - ✔✔1. Static Load: Applied slowly
2. Dynamic Load: Applied suddenly
6 Types of static loads - ✔✔1. Live load (Occupant / Snow)
2. Dead load (self weight / mech)
3. Settlement loads (diff settlement)
4. Ground pressure (soil mass)
5. Hydrostatic Pressure
6. Impact load
2 Types Dynamic Loads - ✔✔1. Wind
2. Earthquake
Shear Strength Soil - ✔✔Ability to resist displacement when forces applied
1 - Cohesive soils (clay, silt) retain strength when unconfined (high angle of repose)
2 - Non cohesive soils (gravel, sand) require confined forces and have shallow angle of repose
Structural stresses - ✔✔1. Compression
2. Tension
3. Shear
4. Bending
5. Torsion (twisting)
Heating and cooling loads - ✔✔1. Heating load: Heat loss btu/hr
2. Cooling load: Heat gain btu/hr
, Test for soil permeability - ✔✔Percolation test
Septic system distances - ✔✔Tank and Field
1. From wells - 100' (30m)
2. From Streams - 50' (15m)
3. From PL or Buildings - 10' (3m)
Septic Tank Drainage - ✔✔1 - Drainage field: Absorption trenches that drain into field, seeps
into soil
2- Seepage Pit: Use when soil is absorbent and water table 2'-0" below pit
3 - Subsurface sand filter: Use when the other two can't be used. Distribution pipes surrounded
by graded gravel
Heating systems - ✔✔1. Forced air
2. Hot water
3. Electrica
4. Radiant
5. Active solar
Forced Air Heating - ✔✔Pros:
- Most commonly used
- cost effective
- simple
- easy to service, versatile
Cons:
- Space required,
