Answer: 0.053
Explanation:
So, we convert 5.3 grams into kilograms.
5.3g = 0.0053 kg (Since 1kg equals 1000g)
On Earth, gravity is 10 N/kg.
Weight = mass x gravity
Weight = 0.0053kg x 10 N/kg
Weight = 0.053 Newtons (On Earth)
Answer:
Minimum Allowable diameter for each of the 5 bolts = 0.0394 m = 3.94 cm
Explanation:
Maximum Working Stress = Ultimate Shear Stress/factor of safety
Maximum Working Stress = 280 MPa/3.8 = 73.68 MPa
Working Stress = Applied load/Minimum allowable Area = L/A
Minimum Allowable Area = Applied Load/Maximum Working Stress
A = 450000/73680000 = 0.00611 m²
This area is supplied by 5 bolts, so each bolt supplies A/5 = 0.0061/5 = 0.00122 m²
Cross sectional Area of bolts = πD²/4
0.00122 = πD²/4
D² = 4 × 0.00122/π = 0.00155
D = √0.00155 = 0.0394 m = 3.94 cm
Each of the five bolt can have a minimum diameter of 3.94 cm
Hope this Helps!!!
Answer:11.602 KW
Explanation:
mass of vehicle
speed=40Km/h
Resistance=600 N
Gear ratio
Net force to overcome by engine is
F=Resistance + sin component of weight
F=600+
Where ![tan\theta =[tex]\frac{1}{50}](https://tex.z-dn.net/?f=tan%5Ctheta%20%3D%5Btex%5D%5Cfrac%7B1%7D%7B50%7D)
F=600+235.38=835.38 N
power=
Engine Power=
=11.602 KW
Answer: When walking with a sharp tool, the tool should be carried with the blade down and away from the body. When climbing with a sharp tool, tool belts, or buckets with hand lines should be used so workers can have both hands to grip the ladder.
