Question: a traffic light consists of a horizontal member attached to...

Question details

A traffic light consists of a horizontal member attached to a vertical support post. The horizontal member extends 7 m to the left of the support post and has a constant mass density of 15 kg/m. Each traffic light has mass of 10 kg, and the street sign has a mass of 4.5 kg. Make sure the connection between the horizontal member and the vertical support post is strong enough to withstand the forces exerted on the horizontal member. Calculate the effects of the forces resulting from the two traffic lights and the street sign on the horizontal member Main St.

To determine the overall rotational effects on the horizontal member all of the summed on the horizontal member must be forces

Which of the following equations can be used to determine the net weight force on the horizontal member? Use the coordinate system specified in question 4. Let the positions along the x-axis at which the left and middle traffic light fixtures are located be xight and xight2, respectively. The position of the street sign is Xsign OFy-mlight1 9 ightlmight2 g- Tlight2 + msign 9 Esign mmember 9.member OFymlightl g- mlight2 9- msign 9- mmember g 0 ГРУ -mlightl . g. 2 lightl-mlight2 . g. 2 light2-msign , g. zsign-m member . g.Zn ember OFy-mlightl + mlight2 + msign +mmember

Using the correct expression from question 5, calculate the net weight force on the horizontal member of the traffic light. The net weight force is determined to be 1275 N
