a cutting diagram shows how parts should be arranged so they can be produced with the minimum number of cuts?

A traffic control engineer reports that 75% of the vehicles passing through a checkpoint

are from within the state. What is the probability that fewer than 4 of the next 9 vehicles

are from out of state?

A solid cylinder, 0 ≤ r ≤ b, is initially at zero temperature. For times t > 0, internal energy is generated in the solid at a rate of g(t) per unit volume (W/m3), whereas the boundary surface at r = b dissipates heat by convection into a medium at zero temperature. Obtain an expression for the temperature distribution T(r,t) in the cylinder for times t > 0.

A 50 m steel tape was used to lay out a 500 m race track. During taping, the temperature was 32 deg C and the pull applied throughout was 8 kg. If the tape is of standard length at 15 deg C and a pull of 6 kg, what should be the correct length to layout considering corrections for temperature and pull?

what will be the mass of a certain gas if it subjected to a 6 meter diameter pressurized cylindrical container at 40 degree celcius and 110 kpa the gas is initially measured from its standard temperature and pressure which calculated its density to be 4 kg/m^3 the height of the container is 6 meters

Inductance of moving iron instrument is given by L=(12+6ø-ø2)µH Where ø is the Deflection in radians from zero position. The spring constant is 12*10-6 Nm/Rad. calculate the Deflection for current of 8 amp.

an electric hot plate is maintained at a temperature of 350 degrees Celsius and is used to keep a solution just boiling at 95 degrees Celsius

A vehicle travelling at 70km/hr is accelerating up a hill with a gradient of 1 to 20. If the mass of the car is 1500kg, the frontal area is 1.95m², rolling resistance of 240N and the drag coefficient of the body if 0.035. At this instant, the engine is developing 56.80KW at 4000rev/min and the transmission efficiency is 80%. If the rear axle ratio is 5.2 to 1 and the rolling radius is 35cm. Calculate the acceleration of the vehicle. (Take TR-RG + RR+ RA

The diameter of a brake drum is 30cm the pivot for the brake shoe and the point of application of the force actuating the shoe are 120mm each from the axis of rotation. Assume that the pressure distribution over the brake lining is equal to a single force acting radially and the coefficient of friction is 0.25. Calculate the braking torque exerted by an operating force of 900N on:

i. The leading shoe

ii. The trailing shoe
