An alternative technique for minimizing impact loads under the previously mentioned conditions can be_________________?
Show answer Hide answer
Answer: B. to increase length
Explanation
Increasing the overall length of a stressed member enhances its total elastic resilience and energy storage capacity. A longer fastener stretches more under impact loads, lowering peak shock stress levels transmitted to the joint. This increased compliance protects structural components from brittle failure during severe dynamic loading events. Resilience measures the capacity of a material to absorb energy when deformed elastically. Shock loads generate high instantaneous forces that can be mitigated by increasing mechanical component compliance. Hooke law dictates that longer elastic members experience lower stress for identical displacement values.
Engine connecting rod bolts are designed with adequate length and reduced shanks to absorb firing shock loads. Structural foundation anchor bolts incorporate long elastic shanks to withstand seismic impact forces safely. Mechanical designers increase fastener lengths when joints face severe cyclic impact operating conditions. Decreasing member length increases stiffness, causing higher peak stress spikes during impact loading. Stating impact resistance is unaffected by length ignores fundamental elastic deformation and energy formulas. Claiming other factors decide the outcome neglects the proven engineering principle of length-induced compliance.

Show answer Hide answer
Answer: A. direction of twist of wires in strands is opposite to the direction of twist of strands
In ordinary cross-laid wire ropes, the direction of twist of wires in strands opposes the strand twist. This opposing twist prevents the wire rope from unravelling under tension during operation. Cross-laying provides st...

Lubricating oil in a journal bearing must be introduced directly at the location where the applied load is lightest. Introducing oil at the point of minimum pressure allows the lubricant to enter easily without fighting...
Q4. For an elastic bar secured at its upper end and impacted by a falling weight at the bottom, the resulting shock load magnitude can be diminished by_________________?
Show answer Hide answer
Answer: A. decreasing the cross-section area of’ bar
Decreasing the cross-sectional area of an elastic bar increases its compliance and resilience. Higher resilience allows the bar to store more impact energy per unit volume elastically. This increased ability to stretch r...
