Answer:

A block and tackle is characterized by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load. Its mechanical advantage is the number of parts of the rope that act on the load. The mechanical advantage of a tackle dictates how much easier it is to haul or lift the load.

Match the benefit of full synthetic oil with engine conditions: All engines
mart [117]

Answer:

1. All engines  exhibit wear over time ⇒ <em>Synthetic Improves engine protection by resisting oil breakdown.</em>

Synthetic oil does not breakdown so easily which means that it protects the engine more and protects it from wearing.

2. Engines are cold at start-up and not while running ⇒ <em> Synthetic provides maximum protection in extreme hot and cold temperature conditions.</em>

By providing protection for the engine during cold and hot conditions, the engine will not be too cold when the car is started up.

3.  If oil is thicker, engines lose power and efficiency ⇒ <em>Synthetic has greater resistance to oil thickening to maintain engine efficiency.</em>

Part of the characteristics of synthetic oil is that it does not get as thick as regular oil which means that the adverse effects of thick oil are spared on the engine.
