Answer:
true
Explanation:
Creep is known as the time dependent deformation of structure due to constant load acting on the body.
Creep is generally seen at high temperature.
Due to creep the length of the structure increases which is not fit for serviceability purpose.
When time passes structure gain strength as the structure strength increases with time so creep tends to decrease.
When we talk about Creep rate for new structure the creep will be more than the old structure i.e. the creep rate decreases with time.
Answer:
The world wars. Most notably world War II
Explanation:
The demand for aircrafts during these events led to extensive research into the design of aircrafts. Aircraft advanced within these years from a simple design to a more complex design; capable of carrying fire power and even became bomb equipped. Also, the material of choice of production moved from wood to metal and the engine was improved on to gain more speed and maneuverability.
Answer:
5.70 m
Explanation:
3sₐ + sB = L
3∆sₐ = - ∆sB
3vₐ = -vB
3*3 = -vB
vB = -9 ms⁻²
T₁ + V₁ = T₂ + V₂
(0 + 0) + (0 + 0) = 1/2(20)(3)² + 1/2(30)(-9)² + 20*9.81*(sB/3) + 30*9.81* sB
0 = 90 + 1215 - 228.9sB
-1305 = - 228.9sB
sB = 1305/228.9 = 5.70 m

Explained
Explanation:
Analytical methods are used for Risk management in the system's engineering department and it is therefore, important to be familiar with it. Many processes and practices such as identifying, measuring, managing risks in engineering systems are done using these analytical methods. In all types of systems analytical methods such as analyzing and measuring are needed. It also helps in risk aversion and risk reduction by balancing risk. Also the decision making is becomes better when these methods are employed. In advanced as well as traditional systems there is a need to manage risk and these methods are always beneficial in doing that.
