A 4.0 in. wide by 1.125 in. thick rectangular steel bar supports a load of P in tension. Determine:
• The stress in the bar for F = 32,000 lb.
• The load P that can be supported by the bar if the axial stress must not exceed 25,000 psi.
Answer:
a) The stress in the bar when F is 32,000 is approximately 7,100 psi
b) The load P that can be supported by the bar if the axial stress must not exceed is approximately 110,000 lb
Explanation:
The question topic relates to stresses in structures;
The given parameters of the steel bar are;
The width of the steel bar, W = 4.0 in.
The thickness of the steel bar, t = 1.125 in.
The formula for stress in a bar is given as follows;
[tex]Stress, \sigma = \dfrac{Force, F}{Area, A}[/tex]
The cross sectional area of bar, A = W × t = 4.0 in. × 1.125 in. = 4.5 in.²
∴ The cross sectional area of bar, A = 4.5 in.²
a) The stress in the bar for F = 32,000 lb, is given as follows;
[tex]The \ stress \ in \ the \ bar , \sigma = \dfrac{ F}{A} = \dfrac{32,000 \ lb}{4.5 \ in.^2} = 7,111.\overline 1[/tex]
The stress in the bar when F is 32,000 is σ = 7,111.[tex]\overline 1[/tex] psi ≈ 7,100 psi
b) The load P that can be supported by the bar if the axial stress must not exceed, σ = 25,000 psi is given as follows;
[tex]\sigma = \dfrac{ P}{A}[/tex]
Therefore;
P = σ × A = 25,000 psi × 4.5 in² = 112,500 lb
For the axial stress of 25,000 psi not to be exceeded, the maximum load that can be supported by the bar, P = 112,500 lb ≈ 110,000 lb.

) How can
we produce organic vegetables. Enplain briefly
Answer:
Use natural substances in a garden
Explanation:
Organic producers rely on natural substances. Organic food is produced without using most conventional pesticides such as human made pesticides and fertilizers made with synthetic ingredients or sewage sludge, bioengineering, or ionizing radiation. Have a sunny place for your garden, soil, and water to keep the plants healthy.
In addition to bandages and gauze, it's recommended that a first aid kit also contain
