Please determine if the following statement is true or false, and explains why.

1. Effective stress is defined as total stress minus pore pressure.

2. For a given consolidation stress, a normally consolidated clay will be stronger than an overconsolidated clay.

Expert Solution

1. True

Total stress is due to self wight if soil(wieght of solid + weight of water) or due to applied overburden pressure.

Pore water pressure = is the pressure which is being transmitted by pore fluid and is which is equal to qeight of fluid.

Effective stress = it is stres which is being transfered in soil mass by grains to grains which tends to force the particles to come into close state of contact.

Hence we can say Effective stress = total stress - pore water pressure

Hence effective stress = total stress - pore water pressure

2. false

Because Normally consolidated soil is going to deform under a certain pressure but over consolidated soil is already deformed under that pressure if that is preconsolidation pressure.

Hence Normally consolidated soil is weaker than over consolidated soil.

Determine whether the statement is true or false. If it is false, explain why or give an example that shows it is false. If f(c) = L,then lim x→c f(x) = L. False. Define f to be the piece-wise function where f(x) = x + 3 when x ≠ −1 and f(x) = 2 when x = −1. Then we have f(−1) = 2 while the limit of f as x approaches −1 is equal to −2. False. Define f...

True or False Questions: Determine if true or false. If false why? 1) Premature efforts to treat problem behavior before determining its function can be inefficient, ineffective, and even harmful. 2) Research has found that functional analyses conducted in natural environments (e.g., classroom settings) often yield the same (or even clearer) results compared to those conducted in simulated settings. 3) Problem behavior can only be maintained by one function. Behaviors are not multi-functional. 4) Indirect functional assessment procedures are referred...
