Answer:
Cinder blocks
Explanation:
From safety training guides, whenever there is inadequate support, poor
construction, or a movement in the components of the
scaffold such as the coupler as well as the base upon which the
scaffold structure is built, there will be a great danger of collapse.
In light of this safety rule, Cinder blocks such as sandcrete blocks, bricks e.t.c shouldn't be used to support scaffold because they
have a high tendency of being crushed under load
Answer:
a. Stored energy is potential energy, and energy of motion is kinetic energy
Explanation:
The correct option is - a. Stored energy is potential energy, and energy of motion is kinetic energy.
Reason -
Potential energy is stored energy, whereas kinetic energy is the energy of moving things.
- Kinetic energy is energy possessed by an object in motion.
- The energy associated with position is called potential energy .
This is the reason why dimensional analysis is very important. It is a technique used that only involves operations with units. You disregard the quantities first. The concept is to make sure that the final answer of your calculations must be consistent of what is asked. Similar units are cancelled when they appear both on the numerator and denominator side. If the mathematicians used this, they could've prevented the crash from happening. What good would the calculations bring if you are not consistent with the units?
Answer:
the formula of mechanical advantage is
MA = load / effort
VR = effort distance / load distance
