Option c is correct. Hole filling fasteners (for example, MS20470 rivets) should not be used in composite structures primarily because of the increased possibility of fretting corrosion in the fastener.

Fretting corrosion is the outcome of simultaneous physicochemical and mechanical surface interaction in a tribological contact, and it is the irreversible change of a material. A specific load and cyclic displacement with a limited amplitude must be applied to the contact between the surfaces of two materials for fretting corrosion to take place.

Small gaps develop between the surfaces in contact as a result of cyclic tension. Either material is lost or cracks start to appear as a result. Fretting corrosion's side effect of contact corrosion almost always causes a blockage because the lack of functional movement makes it impossible to remove debris. When debris is still trapped, there is blockage because the oxide takes up more space than the original material.

Does the Diesel engine have engine knock or detonation problem? Why?

Luda [366]

Explanation:

Yes Diesel engine have problem of knocking.

We know that knocking is phenomenon in which suddenly large amount of power generates this large amount of power will cause the failure of diesel engine.

Actually when one set of fuel inject inside the cylinder to burn with already compressed air (in general up to 10-15 bar) then this fuel does not burn complete and accumulate inside the cylinder.After that second set of fuel inject inside the cylinder then that one set of fuel burns with second set of fuel and produces large amount of sudden power for engine and causes the breaks in the crank or connecting rod of engine.it leads to damage the engine.

True

Explanation:

Dual home host - it is referred to as the firewall that is incorporated with two or more networks. out of these two networks, one is assigned to the internal network and the other is for the network. The main purpose of the dual-homed host is to ensure that no Internet protocol traffic is induced between both the network.

The most simple example of a dual-homed host is a computing motherboard that is provided with two network interfaces.

The maximum stress that a bar will withstand before failing is called • Rapture Strength • Yield Strength • Tensile Strength • B

konstantin123 [22]

Answer: Rupture strength

Explanation: Rupture strength is the strength of a material that is bearable till the point before the breakage by the tensile strength applied on it. This term is mentioned when there is a sort of deformation in the material due to tension.So, rupture will occur before whenever there are chances of failing and the material is still able to bear stresses before failing.
