Concept explainers

Connections

In steel structures, connections are the members that join two or more steel members. The connections are the most important members of any steel structure, and hence, they are designed more carefully. The majority of the construction cost of steel structures is incurred due to the connections. The design of connections is done as per the recommendations and specifications of the American Institute of Steel Construction (AISC).

Question

Two helicopters, H1 and H2, are traveling together. At the time t 0, they separate
and follow different straight line paths given by
H1:
x = 6+ 40t
y = -3+ 10t
z = -3+2t
H2:
x 6+ 110t
y = -3+ 4t
z = -3+t
Time t is measured in hours and all coordinates are measured in miles. Due to an error,
H2 stops its flight at (446, 13, 1) and lands at (446, 13, 0). Two hours later, H is
informed about H2 and moved toward H2 at 175 mph. How long will it takes Hi to reach
H2?
