A dump truck is shown in the figure. The loaded container has a mass of 8000 Kg and may be modelled as a solid homogeneous block. The hydraulic cylinder applies a force of 300 kN to the container in the starting position shown. Calculate the initial angular acceleration of the container for the following conditions:
a. if the truck is not moving, b. if the truck has a forward acceleration of 3 m/s2.
Air enters an adiabatic duct of L/D = 40 at V1 = 170 m/s and T1 = 300 K. The flow at the exit is choked. What is the average friction factor in the duct?
Draw the T-s diagram (hint: it would help to begin with a schematic of the cycle) and.
What is the best approach to learn programming directed towards numerical methods and CFD for a beginner.
steam with 88.6% quality and a flow rate of 750 kg/s enters a condenser operating @ 75 KPa. Saturated liquid leaves the condenser. How much heat is rejected to the cooling system.
Two solid cylindrical rods (1) and (2) are joined together at flange B and loaded. If the normal stress in each rod must be limited to 110 MPa, determine the minimum diameter D required for each rod.
two spinning discs have the same angular momentum, but disk 1 has more kinetic energy than disk 2. Which one has the bigger moment of inertia - explain your reasoning?
What will be the length of the specimen after the load is removed? d) The specimen was reloaded until fracture. If the % reduction in area after fracture was 40%, what is the minimum diameter of the specimen at fracture?
Describe how you would implement it using an open-loop system
Why does the definition of NPSH include the dynamic head of the fluid? Isn't cavitation based only on the difference between the static head and the local vapor pressure?
Determine the temperature at which the liquid in the tank is completely vaporized. Also show the process on a T-v diagram with respect to saturation lines.
Each turbine stage isentropic efficiency of 85% FWH is open T-S diagram for cycle? What is thermal efficiency and the moisture content of the steam leaving the low-pressure turbine?
