Maintenance spanner are needed in great numbers to service all sorts of technical equipment
Answer:
- 210 rad/s²
Explanation:
n = frequency of rotation = 3400/60 = 170/3 per sec.
angular velocity ω ( 0 ) at time 0 = 2π n = 2π x 170/3
angular velocity at time t = ω(t) = 0
now, ω²( t) = w²(o) + 2α Φ ( α = angular acceleration and Φ = angular displacement) = 2π x 48 rad.
0 = ( 2π x 170/3 )² + 2α x 48 x 2π
α = - (2π x 170 x 170 )/ (3 x 3 x 2 x 48 ) = 210 rad / s²

I hope my answer helped you.
The direction of friction force is always the opposite of the direction of the movement.
In this problem, we have an applied force of 20N and this creates a movement. Then, the friction comes in and applies a force of 2.4N.
Because they are in different directions, we need to subtract them:
We don't know the direction because there is no picture (at least I can't see ☺️). But the movement will be to the direction of the 20N.
A. a lever
Explanation:
To remove a nail from wood, a lever will be the best machine to use. In a lever, effort is applied to move a large load. The nail is treated as the load.
- Most hammers have nail removers that can be used to pull out nails.
- The force is applied at the handle.
- The head of the hammer has a fulcrum and nail remover part where the load is.
- This gives a large mechanical advantage and the nail can be pulled out.
- Wedge, wheel and axle and movable pulley are not machines that works as nail removers.
