Question

(FIXED)
Evaluate the following expressions given the functions below:
g(x) = -3x + 1

f(x) = x2 + 7

h(x) = 12/X

j(x) = 2x + 9


a. g(10) =

b. f(3) =


c. h(–2) =

d. j(7) =

e. h(a)

f. g(b+c)

Answer 1

Step-by-step explanation:

(c)

p = ~3EJx(a+b)1 ma2b2;

p = ~/l2EJx Ima2(4a+3b);

p = ~(cl +3EJx I mI3).

Ins t r u c t ion. In accordance with the force method, the canonical form of the differ-

ential equation of motion for a system with the single degree of freedom is

y = 811 (-my).

Here, 811 is the displacement of the load under the action of a unit force in the direction

coinciding with this displacement. Therefore, the frequency of free vibrations is

p =11 Jm811 •

(a) p =~EJx Im13 ;

(b) p = ~48EJx I 7ml3 ;

(c) p = ~6EJx I mh2(h+b);

(d) p = ~12EJx Ima2 (4a+3b).

As an example of the determination of the compliance (coefficients for stati-

cally indeterminate systems), we consider Problem 2d. Breaking the

constraint (under the assumption that the constraint between the load of mass m

and the base surface is bilateral), we apply the force N (the constraint reaction
