Answer:
293 kg
Explanation:
Let's say the tension in each cable is Tb, Tc, and Td.
First, find the length of cable AD:
r = √(2² + 2² + 1²)
r = 3
Using similar triangles:
Tdx = 2/3 Td
Tdy = 2/3 Td
Tdz = 1/3 Td
Sum of the forces in the x direction:
∑F = ma
Tb − 2/3 Td = 0
Td = 3/2 Tb
Sum of the forces in the y direction:
∑F = ma
2/3 Td − Tc = 0
Td = 3/2 Tc
Sum of the forces in the z direction:
∑F = ma
1/3 Td − mg = 0
Td = 3mg
From the first two equations, we know Td is greater than Tb or Tc. So we need to set Td to 8.6 kN, or 8600 N.
8600 N = 3mg
m = 8600 N / (3 × 9.8 m/s²)
m ≈ 292.5 kg
Rounded to three significant figures, the maximum mass of the crate is 293 kg.

Answer:
F=531831381
Explanation:
There are two ways of doing this question:
1) By Formula
2) By Using Compound interest Table
By Formula:
Where:
F is future value
A is annual amount per year
i is interest rate
n is number of years
F=531831381
By Using Compound interest Table:
F=A(F/A,i,n)
From Table F/A at i=8% and n=8 is 10.6366
F=50000000*(10.6366)
F=531830000≅531831381
The difference in two answers is due to decimal points if you take value from table to greater decimal points you will get the exact answer as by using formula.
It was determined by the forensic engineers that the historic collapse of the Minneapolis Interstate Bridge was due to design and construction flaws. It led to the collapse of the structure.
<h3>What is the Minneapolis Interstate Bridge?</h3>
The Minneapolis Interstate Bridge is a well-known bridge that was constructed in Minneapolis city in 1967.
It has been demonstrated that the collapse of this bridge constructed in Minneapolis was due to its inadequate load capacity.
In architecture, it is fundamental to measure the amount of weight that a structure (in this case, a bridge) can sustain in a given period of time.

Answer:
1200+_10%
Explanation:
The first two bands reresents the first two digits of the resistance value in ohms. This multiplier will shift the decimal place around to change the value from mega ohms to milliohms and anywhere in between. The fourth color band signifies tolerance. Giving a total of
