The information on a can of pop indicates that the can contains 360 mL. The mass of a full can of pop is 0.369 kg, while an empty can weighs 0.153 N. Determine the specific weight, density, and specific gravity of the pop and compare your results with the corresponding values for water at Express your results in SI units.

Answers

Answer 1

Answer:

Answer:

Specific weight of the pop, $w_(s) = 8619.45 N/m^(3)$

Density of the pop, $\rho_(p) = 8790.76 kg/m^(3)$

$g_(s) = 8.79076$

$w_(w) = 9782.36 N/m^(3)$

Given:

Volume of pop, V = 360 mL = 0.36 L = $0.36* 10^(-3) m^(3)$

Mass of a can of pop , m = 0.369 kg

Weight of an empty can, W = 0.153 N

Solution:

Now, weight of a full can pop, W

W' = mg = $0.369* 9.8 = 3.616 N$

Now weight of the pop in can is given by:

w = W' - W = 3.616 - 0.513 = 3.103 N

Now,

The specific weight of the pop, $w_(s) = (weight of pop)/(volume of pop)$

$w_(s) = (3.103)/(0.36* 10^(- 3)) = 8619.45 N/m^(3)$

Now, density of the pop:

$\rho_(p) = (w_(s))/(g)$

$\rho_(p) = (86149.45)/(9.8) = 8790.76 kg/m^(3)$

Now,

Specific gravity, $g_(s) = (\rho_(p))/(density of water, \rho_(w))$

where

$g_(s) = (8790.76)/(1000) = 8.79076$

Now, for water at $20^(\circ)c$ :

Specific density of water = $998.2 kg/m^(3)$

Specific gravity of water = $0.998 kg/m^(3)$

Specific weight of water at $20^(\circ)c$ :

$w_(w) = \rho_(20^(\circ))* g = 998.2* 9.8 = 9782.36 N/m^(3)$

8. 15 A manual arc welding cell uses a welder and a fitter. The cell operates 2,000 hriyr. The welder is paid $30/hr and the fitter is paid $25/hr. Both rates include applicable overheads. The cycle time to complete one welded assembly is 15. 4 min. Of this time, the arc-on time is 25%, and the fitter's participation in the cycle is 30% of the cycle time. A robotic arc welding cell is being considered to replace this manual cell. The new cell would have one robot, one fitter, and two workstations, so that while the robot is working at the first sta tion, the fitter is unloading the other station and loading it with new components. The fitter's rate would remain at $25/hr. For the new cell, the production rate would be eight welded assemblies per hour. The arc-on time would increase to almost 52%, and the fitter's participation in the cycle would be about 62%. The installed cost of the robot and worksta tions is $158,000. Power and other utilities to operate the robot and arc welding equipment will be $3. 80/hr, and annual maintenance costs are $3,500.

In this type of projection, the angles between the three axes are different:- A) Isometric B) Axonometric C) Trimetric D) Dimetnic

Answers

Answer:

The correct answer is C) Trimetric

Explanation:

The most suitable answer is a trimetric projection because, in this type of projection, we see that the projection of the three angles between the axes are not equal. Therefore, to generate a trimetric projection of an object, it is necessary to have three separate scales.
