Because there are no angles for alignment, the round shape makes these heavy covers easier to put back on once they're taken off. Round covers are also easier to manufacture. But the main reason manhole covers are round is so they won't accidentally fall into the manhole itself.
A motor car shaft consists of a steel tube 30 mm internal diameter and 4 mm thick. The engine develops 10 kW at 2000 r.p.m. Find the maximum shear stress in the tube when the power is transmitted through a 4: 1 gearing.
The maximum shear stress in the tube when the power is transmitted through a 4: 1 gearing is 28.98 MPa.
What is power?Power is the energy transferred per unit time.
Torque is find out by
P = 2πNT/60
10000 = 2π x 2000 x T / 60
T =47.74 N.m
The gear ratio Ne / Ns =4/1
Ns =2000/4 = 500
Ts =Ps x 60/(2π x 500)
Ts =190.96 N.m
Maximum shear stress τ = 16/π x (T / (d₀⁴ - d₁⁴))
τ max =T/J x D/2
where d₁ = 30mm = 0.03 m
d₀ = 30 +(2x 4) = 38mm =0.038 m
Substitute the values into the equation, we get
τ max = 16 x 190.96 x 0.038 /π x (0.038⁴ - 0.03⁴)
τ max = 28.98 MPa.
Thus, the maximum shear stress in the tube is 28.98 MPa.

Tech B says that in a four-stroke engine, the piston travels to TDC four times to complete the cycle. Tech B says that in a four-stroke engine, the air-fuel mixture is ignited once every two strokes. Who is correct
Tech B is correct: In a four-stroke engine, the piston reaches TDC twice per cycle, and the air-fuel mixture is ignited once every two strokes.
In a four-stroke engine, the piston travels to Top Dead Center (TDC) two times to complete the entire cycle.
During the first stroke (intake), the air-fuel mixture is drawn into the cylinder, and during the fourth stroke (power), the ignited air-fuel mixture produces power and the piston again reaches TDC.
This means that the piston reaches TDC twice during one complete cycle.
Additionally, Tech B is also correct in stating that the air-fuel mixture is ignited once every two strokes.
The ignition happens during the power stroke (fourth stroke) after the compression stroke (third stroke).
Hence, tech B is correct.

a pipe discharges wine into a 1.5m diameter tank. Another pipe (15cm diameter), located near the base of the, is used to discharge wine out of the tank. Calculate the volumetric flow rate into the tank if the wine level remains constant at 2.5m.
The volumetric flow rate into the tank if the wine level remains constant at 2.5m is; 0.1232 m³/s
How to Calculate Volumetric Flow Rate?The formula for volumetric flow rate is;
V' = area * velocity
We are given;
Diameter; d = 15 cm = 0.15 m
Thus;
Area; A = (π/4)d²
A = (π/4)(0.15)²
A = 0.0176 m²
Velocity is; v = √(2gh)
v = √(2 * 9.8 * 2.5)
v = 7 m/s

A ladder of length l is leaning against a domed roof with a radius r. The base of the ladder is distance d from the base of the dome. The ladder begins to slide. Determine the IC at the moment the ladder slides if:
l = 2 m
r = 1 m
d = 0.5 m

The IC at the moment the ladder slides based on the lengths and other information given will be (0, 1.32)
How to calculate the IC?From the information given, the calculation will be computed below:
l cos a = 1.5
cos a = 1.5/2
cos a = 0.75
a = 41.4°
ab = a/cos a = 1.5/cos41.4
ab = 1.5/0.75

The factor of safety is very important in design. It is determined by comparing the allowable stress to actual stress. What is known if the range of the factor of safety is between .75 and 1
Explanation:
A factor of safety is the load-carrying capacity of a system beyond what the system actually supports. Bridges, buildings, safety equipment, and fall protection all start with a factor of safety.
Simply put, the safety factor is how much stronger a system is than required. The factor of safety is the backbone of all structures and safety equipment and originates with engineers. In the planning phase of all structures and safety equipment, engineers determine the required overload from any object to remain safe in the event of an emergency.
For reliability, structures are typically built stronger than necessary. This is in case a structure experiences a heavier-than-expected load. This is a factor of safety. Ultimately, the amount of stress and overload a structure can handle comes down to the material used to build it.
Determining the factor of safety:
Engineers perform strength tests to determine how much weight a material can handle. Certain materials are more ductile than others, meaning they deform to pressure before breaking more so than others, like brittle materials. Brittle materials simply break once they meet the maximum force.
Ductile materials use yield strength to determine the safety factor. Brittle materials use the ultimate strength.
Yield strength: Determines the safety factor until the start of deformation.
Ultimate strength: Determines the safety factor until failure.
Ductile materials often test the factor of safety against yield and ultimate strengths while brittle materials usually only calculate the ultimate safety factor since the yield and ultimate values are often so close.
The necessary factor of safety of any structure determines the materials used. If a structure has a high required factor of safety, then engineers use a ductile material to build it. The realized factor of safety determines the amount of material used.
Required (design factor): A constant value imposed by law or standard. A structure is required to meet this value at a minimum.
