Question

1) A uniform wooden beam, with mass of 120 and length L = 4 m, is supported as illustrated in the figure. If the static friction coefficients at points A and B ua= 0.3 and ub=0.1 determine the value of the angle so that the system is in equilibrium if (a) =70 and (b)=90

Answer 1

Answer:

figure. If the static friction coefficients at points A and B ua= 0.3 and ub=0.1 determine the value of the angle so that the system is in equilibrium if (a) =70 and (b)=90It all ties back to the fundamental way banks make money: Banks use depositors' money to make loans. The amount of interest the banks collect on the loans is greater than the amount of interest they pay to customers with savings accounts—and the difference is the banks' profit.

Answer 2

Explanation:

Given :-

• A uniform wooden beam, with mass of 120 and length L = 4 m,

• A and B ua= 0.3 and ub=0.1

• if (a) =70 and (b)=90

Solution :-

u 70 = 0.3

u 90 = 0.1

u160 = 3.0
