What causes a light bulb to explode in a thunderstorm?
A sudden lightning strike can induce a power surge in the electrical system, causing the light bulb filament to overheat and explode. The surge can overload the bulb, resulting in the rapid expansion and fragmentation of the filament. It is recommended to unplug electronic devices during a thunderstorm to prevent damage from power surges.
36.6N and 25.9 N respectively.
This will cause the beam to bend. You need to see the beam like a stack of spaghetti.
Extended spagghettis are in tension
Shortened spaghettis are in compression
(equals signs represent the beam, dots represent air)

In this scenario, the vertical cable must support the entire weight of the traffic light, which is 122 N. Since the upper cables can only handle a maximum tension of 100 N before breaking, the system is at risk. To prevent the upper cables from failing, the setup must be adjusted, either by redistributing the load or reinforcing the upper cables to better accommodate the weight of the traffic light.
