Is lean only for manufacturing?
Is lean only for manufacturing? Lean manufacturing is a body of knowledge used to continuously improve processes and deliver value to customers. It has a lot of overlap with industrial engineering and quality engineering, but it is not only for engineers and it is not only for manufacturing. What are lean practices? Lean is defined […]
What component can mask internal engine oil leaks?
What component can mask internal engine oil leaks? Modem engine run at high internal engine temperatures and are also equipped with very efficient catalytic converters. These can mask internal oil leaks. When was motor oil invented? 1866 What can be used as a tracing powder when checking for small oil leaks? Once the engine is […]
What are the 4 types of suspension?
What are the 4 types of suspension? The majority of land vehicles are suspended by steel springs of these types: Leaf spring – AKA Hotchkiss, Cart, or semi-elliptical spring. Torsion bar suspension. Coil spring. What are signs of suspension problems? Some common signs that your suspension system needs a little TLC are: Continued bouncing after […]
What are the methods to reduce stress concentration?
What are the methods to reduce stress concentration? These include: Avoiding sharp corners and only using rounded corners with maximum radii. Sanding and polishing surfaces to remove any notches or defects that occur during forming and processing. Lowering the stiffness of straight load-bearing segments. Placing notches and threads in low-stress areas. Which of the following […]
What is the difference between yield stress and ultimate stress?
What is the difference between yield stress and ultimate stress? Yield stress is the stress at which that the material deforms permanently, ultimate tensile stress is the stress at which it breaks. What happens to a material when it undergoes stress that exceeds its strength? For stresses beyond the elastic limit, a material exhibits plastic […]
Should I record 48KHz or 96KHz?
Should I record 48KHz or 96KHz? Recording: For pop music stick to 48 kHz, but 44.1 kHz is acceptable. For audiophile music or sound design you may prefer 96 kHz. Mixing: Mix sessions should remain at the sample rate of the recording. You will not improve the sound of a project by upsampling a session […]
What are the three main types of control systems?
What are the three main types of control systems? Three basic types of control systems are available to executives: (1) output control, (2) behavioural control, and (3) clan control. Different organizations emphasize different types of control, but most organizations use a mix of all three types. Which is the good features of control system? A […]
What happens when thermosets are heated?
What happens when thermosets are heated? Thermoset polymers do not soften when heated because the molecules are cross-linked together and remain rigid. The chemical bonding formed within a polymer, and the shape of the resulting polymer, affect its properties. Which is thermosetting polymer? A thermosetting polymer, resin, or plastic, often called a thermoset, is a […]
What are the different losses that occur in a steam turbine?
What are the different losses that occur in a steam turbine? Losses due to leakage :- In Impulse turbine, leakage loss occurs between the shaft, bearings, nozzles and stationary diaphragms. For Reaction turbine, it may occur at the blade tips. This loss is due to the leakage of steam on each stage of the turbine. […]
