What is the difference between direct injection and indirect injection?
Expert Solution & Answer
To determine
The difference between direct and indirect injections.
Explanation of Solution
The differences between direct and indirect injections are shown in below table.
| S.No. | Direct injection | Indirect injection |
| 1 | The fuel is directly injected into the cylinder. | The fuel is injected into the cylinder through a pre-chamber by a narrow opening. |
| 2 | The first combustion occurs in the cylinder where the piston experiences a depression. | The first combustion occurs in the pre-chamber. |
| 3 | More efficient and more noise. | Less efficient and less noise. |

A crate weighs 530 lb and is hung by three ropes attached to
a steel ring at A such that the top surface is parallel to the
xy plane. Point A is located at a height of h = 42 in above
the top of the crate directly over the geometric center of the
top surface. Use the dimensions given in the table below to
determine the tension in each of the three ropes.

A block of mass m hangs from the end of bar AB that is 7.2
meters long and connected to the wall in the xz plane. The
bar is supported at A by a ball joint such that it carries only a
compressive force along its axis. The bar is supported at end
B by cables BD and BC that connect to the xz plane at
points C and D respectively with coordinates given in the
figure. Cable BD is elastic and can be modeled as a linear
spring with a spring constant k = 400 N/m and unstretched
length of 6.34 meters.
Determine the mass m, the compressive force in beam AB
and the tension force in cable BC.
