Lab safety equipment prevents damage from accidents and helps keep the people working in the lab safe. The equipment goes hand in hand with the clothing of the person. The first step would be to wear closed shoes and a lab coat.
The equipment that must be worn are goggles to protect the eyes from irritants and latex gloves to protect the skin on the hands.
Answer:
F = 150.6 N
Rx = 63.65 N
Ry = - 115.5 N
orientation is - 61.14 degree with horizontal
Explanation:
given data
moment arm m = 2 cm
angel = 115 degree
distance = 13 cm
force = 21 N
to find out
muscle force, vertical component force , horizontal component force , orientation
solution
we consider here Ra and Rb is reaction upside and
we know moment formula that is
moment at joint = F × sin(θ) × m - force × distance
0 = F × sin(115) × 2 - 21 × 13
F = 150.6 N
so
for horizontal component
sum of horizontal force = Rx + Fcosθ
0 = Rx + (150.6) cos115
Rx = 63.65 N
and
for vertical component
sum of vertical force = Ry + Fsinθ
0 = Ry + (150.6) sin(115)
Ry = - 115.5 N
and
reaction direction are
tan∅ = Ry / Rx
tan∅ = -115.5 / 63.65
∅ = - 61.14 degree
so orientation is - 61.14 degree with horizontal

<span>Average velocity can be calculated by determining the total displacement divided by the total time of travel. The average velocity of an object does not tell us anything about what happens to it between the starting point and ending point. Average velocity is different from average speed because it considers the direction of travel and the overall change in position.</span>
Answer:
88m west and 50m north
Explanation:
1. Find the components of each vector in x and y:
(Please see the picture below)
- Vector 1:
Fx = 52m
Fy = 0m
- Vector 2:
Fx = 44m*cos34.6
Fy = 44m*sin34.6
- Vector 3:
Fx = 0m
Fy = 25m
2. Find the components of the final displacement acting in x and y:
For west direction:
Rx = 52m + 44m*cos34.6 + 0
Rx = 88m
For north direction:
Ry = 0 + 44m*sin34.6 + 25m
Ry = 50m
