Answer
Explanation:
so the velocity is 39 feet per sec so the impact is 720 cm from the ground
take 720 * 39 sq

Answer:
The correct answer is "
".
Explanation:
Given:
Maximum load,
P = 50,000 N
Crack length,
a = 3mm
or,
= 3×10⁻³ m
Diameter,
d = 32 mm
As we know,
⇒ Maximum stress, 


Now,
⇒ Fracture tougness, 
On substituting the values, we get


Answer:
(b) Constant (minimum) volume
Explanation:
In the idealized Otto cycle there are 4 process that are
- Reversible adiabatic compression
- Addition of heat at constant volume
- Reversible adiabatic expansion
- Rejection of constant volume
So from above discussion we can see that heat is added when there is constant (minimum) volume which is given in option (b) so option (b) will be the correct answer
