Shear stress is zero when bending moment is maximum due to the distribution of forces in the cross-section of the beam.

• Shear stress is the force per unit area acting parallel to the cross-section of the beam.

• Bending moment is the internal moment that causes a beam to bend.

• When the bending moment is maximum, the forces are distributed in a way that results in zero shear stress at that point.

• This is because the shear stress and bending moment are related through the shear force...read more

Designing the exhaust system of a mining truck involves considering factors like emissions regulations, engine performance, and durability.

• Research emissions regulations to ensure compliance

• Consider the engine size and power output for optimal performance

• Select materials that can withstand harsh mining environments

• Design the system for easy maintenance and repair

• Include features for noise reduction and heat dissipation

Metal placed in Antarctica would react by becoming extremely cold and potentially brittle due to the low temperatures.

• Metal would quickly reach the temperature of its surroundings, which can drop below -60 degrees Celsius in Antarctica.

• The extreme cold can cause the metal to become brittle and more prone to fracturing.

• Certain metals may undergo phase changes or exhibit changes in electrical conductivity at such low temperatures.

• Corrosion may be slowed down due to the lack of ...read more

Shear stress is the force per unit area perpendicular to the material's cross-section, while bending moment is the internal moment that causes a beam to bend.

• Shear stress is calculated as force divided by area (τ = F/A)

• Bending moment is calculated as force multiplied by distance (M = F * d)

• Shear stress causes deformation parallel to the force applied, while bending moment causes deformation perpendicular to the force applied

• Shear stress is important in determining the strengt...read more

NPV (Net Present Value) is a financial metric that calculates the difference between the present value of cash inflows and outflows. IRR (Internal Rate of Return) is the discount rate that makes the net present value of all cash flows from a particular project equal to zero.

• NPV helps in determining the profitability of an investment by comparing the present value of expected cash inflows with the present value of expected cash outflows.

• IRR is the rate at which the net present...read more

Shear stress is zero when there is no force applied parallel to the surface.

• Shear stress is zero in static fluids, where there is no movement or deformation.

• At the boundaries of a fluid at rest, shear stress is zero.

• In a material with no viscosity, shear stress is zero.

• Shear stress is zero at the center of a pipe with fluid flowing through it.

• In a solid material under pure normal stress, shear stress is zero.

The control scheme for a self driving cart braking motor involves sensors, actuators, and a feedback loop to adjust braking force.

• Utilize sensors to detect obstacles or changes in speed

• Implement an actuator to apply braking force

• Create a feedback loop to adjust braking force based on sensor inputs

• Consider safety mechanisms to prevent sudden stops or collisions
