Answer:
10.007
Explanation:
Assuming we have to find out the compression ratio of the engine
Given information
Cubic capacity of the engine, V = 245 cc
Clearance volume, V_c = 27.2 cc
over square-ratio = 1.1
thus,
D/L = 1.1
where,
D is the bore
L is the stroke
Now,
Volume of the engine V =
plugging values we get
245 =
Solving we get D =7 cm
therefore, L= 7/1.1 =6.36 cm
Now,
the compression ratio is given as:
r =(V+V_c)/V_c
on substituting the values, we get
r = (245+27.2)/27.2 =10.007
Hence, Compression ratio = 10.007
Answer:
I 10 u v 2 because its all equal to the squares. Sorry I dont know if this is correct but I did try to calculate it :)

Answer:
D = 0.060732 in
Explanation:
given data
sp. wt. = 500 lb/ft³
diameter = 0.036 in
solution
we get here maximum diameter of rod that is express as
D = ......................1
here surface tension of water at 60⁰f = 5.03 × lb/ft and y = 500 lb/ft³
so put here value and we will get
D =
D = 0.005061 ft
D = 0.060732 in
