Dec 03, 2019 · 10 disadvantages of friction. Friction has advantages as well as disadvantages. Friction is undesirable when moving at high speeds because it opposes the motion and thus limits the speed of moving objects. Most of our useful energy is lost as heat and sound due to the friction between various moving parts of machines.

Timber post and beam construction - Designing Buildings Wiki - Share your construction industry knowledge. Timber post and beam construction is a building method that comprises vertical structural posts and horizontal beams, jointed to form a structural frame into which walls are ‘placed’. As this frame is structural, and carrying the roof load, the number of interior walls can be reduced ... Spur Gear. Advantages. They offer constant velocity ratio. Spur gears are highly reliable. Spur gears are simplest, hence easiest to design and manufacture. A spur gear is more efficient if you compare it with helical gear of same size. Spur gear teeth are parallel to its axis.
