Link BD consists of a single bar 30 mm wide and 12 mm thick. Knowing that each pin has a10 mm diameter, determine the maximum value of the average normal stress in the link BD if θ = 15 degrees.

Link will be apear in 30 seconds.

Well done! you have successfully gained access to Decrypted Link.

The snapshots of the program source code and the output is provided below. The source code is provided at the end.

Note:-

1. The main function asks the user to enter the length and width of the plot and passes them as argumnets to the "recommended_litres_fertilizers()" function.

2. The length and width of the plot are passed as arguments to the "recommended_litres_fertilizers()" function. The function calculates the recommended number if litres of fertilizer and returns it to the main function.

Algorithm:-

function recommended_litres_fertilizers(length , width):

area <- length*width;

litres_required <- (area/140);

recommended_litres_required <-(litres_required*1.01400);

return recommended_litres_required;

In case any error is encountered while executing the program , inform in the comments.

Output:-

Source code:-

def recommended_litres_fertilizers(length,width): #length and width of the plot are passed as parameters
    
    total_area = length*width #area of the plot

    fertilizer_required = (total_area/140) # 1 litre of fertilizer if required for 140 metres square of area 

    recommended_amount = fertilizer_required*1.01400
    return recommended_amount
