Answer:
Minimum Allowable diameter for each of the 5 bolts = 0.0394 m = 3.94 cm
Explanation:
Maximum Working Stress = Ultimate Shear Stress/factor of safety
Maximum Working Stress = 280 MPa/3.8 = 73.68 MPa
Working Stress = Applied load/Minimum allowable Area = L/A
Minimum Allowable Area = Applied Load/Maximum Working Stress
A = 450000/73680000 = 0.00611 m²
This area is supplied by 5 bolts, so each bolt supplies A/5 = 0.0061/5 = 0.00122 m²
Cross sectional Area of bolts = πD²/4
0.00122 = πD²/4
D² = 4 × 0.00122/π = 0.00155
D = √0.00155 = 0.0394 m = 3.94 cm
Each of the five bolt can have a minimum diameter of 3.94 cm
Hope this Helps!!!
1 liter = .264 gallon
1 km = .621 mile
this means that 58.3km/L is equal to 137.13mpg
so
500/137.13 = 3.65 gallons of gas
3.65 x 3.5 = $12.78

Hello!
To solve this problem you must follow the following steps, which are fully registered in the attached image.
1. Draw the complete outline of the problem.
2. Through laboratory tests, thermodynamic tables were developed, these allow to know all the thermodynamic properties of a substance (entropy, enthalpy, pressure, specific volume, internal energy etc ..)
through prior knowledge of two other properties.
3. Use temodynamic tables to find the density of water in state 1, by means of temperature and quality, with this value and volume we can find the mass.
3. Use thermodynamic tables to find the internal energy in state 1 and two using temperature and quality.
4. uses the first law of thermodynamics that states that the energy in a system is always conserved, replaces the previously found values and finds the work done.
5. draw the pV diagram using the 300F isothermal line
Answer:
D = 0.060732 in
Explanation:
given data
sp. wt. = 500 lb/ft³
diameter = 0.036 in
solution
we get here maximum diameter of rod that is express as
D =
......................1
here
surface tension of water at 60⁰f = 5.03 ×
lb/ft and y = 500 lb/ft³
so put here value and we will get
D =
D = 0.005061 ft
D = 0.060732 in
