For heavy-duty vehicles, sintered-metal brake linings
are typically use for better performance and brake lining rivets is the best
choice to secure brake shoe linings on trucks and other vehicles. Sintered brake
linings offers a stable friction coefficient and produce good bite right away
for safer travel. Moreover, they
have good properties such as the ability to handle extreme heat well, they are
resistant to fade, typically last longer than other types, and perform well
even in rain and mud, which make it to be a choice for heavy-duty vehicles. <span>However, rivet heads may score the drum if the linings
are not replaced soon enough, so proper maintenance should not be neglected.</span>
Answer:
a) 16%
b) 2.25
c) Increase in expected market risk premium
Explanation:
Expected standard deviation of market return = 20%
measure of risk aversion ( A ) = 4
a) Determine a reasonable expected market risk premium
= A * ( std ) ^2
= 4 * ( 20%)^2
= 16%
b) determine Value of A
market risk premium = A * ( std )^2
∴ A = 9% / ( 20% ) ^2
= 0.09 / 0.04
= 2.25
c) If investors become more risk tolerant the expected market risk premium will increase
Answer:
Lock
Explanation:
Locks is a mechanism to avoid the access of records from interacting with one another either in the form of user objects for example tables and/or rows or system objects not cannot be seen by the user such as data shared in memory.
The system (Oracle) obtains all the required locks when executing the transaction request so as to avoid any hassle faced by the user and so that they don't require to be bothered by it. This way the system provides both highest degree of data monitoring with lowest restriction.
Moreover, a fail safe data integrity is provided by the system in case of any failure. This lock can also be done manually by the user.
