Answer:
Yellow, green, polka dot and white jerseys
Explanation:
Tour de France is the biggest bicycle race in the world held at France over a period of 23 days. At the end of each day of racing they give to the certain riders FOUR different colored jerseys:
- The yellow jersey is given to the overall winner at each stage, this shows the rider who was the best in the previous stage.
- The green jersey is given to the best sprinter of each stage,
- The polka dot jersey is given to the rider who first reach the crest of designated hills and mountains at each stage.
- The white jersey is given to the fastest rider at each stage under 25 years at the beginning of the racing year.
At the end of the competition, the total points are counted and the different jerseys are given to the overall winners.
Answer:
- 256 lbs
Explanation:
The internal axial load at point D can be calculated as the change in the subjected loads. if the magnitude of the horizontal direction = zero
; Then:
internal axial load at point D = Δ P
= -(P₂ - P₁)
= - ( 888 lbs - 632 lbs)
= - 256 lbs
The maximum possible force of static friction between two surfaces is given by:
F = μN
F = max friction force, μ = coefficient of static friction, N = normal force
The normal force N equals the object's weight:
N = mg
m = mass, g = gravitational acceleration
Make a substitution:
F = μmg
Given values:
F = 500N, m = 100kg, g = 9.8m/s²
Plug in and solve for μ:
500 = μ(100)(9.8)
μ = 0.51
