Question

**If the allowable deflection for the truss is L/400,
where L is the clear span, does your truss need to be
re-designed?**

Answer #1

**Solution:**

Your truss need **not** to be re-designed, if the
allowable deflection for the truss is L/400, where L is the clear
span.

**Explanation-**

Generally, for roof trusses, the deflection in inches cannot exceed and due to total load . And for floor trusses, the deflection due to live load cannot exceed and due to total load .

In this case, the allowable deflection for the truss is L/400, which will give less value then the above criteria. So the design of truss is safe.

Find the spindle size, optimum span of bearings (L.),
deflection (6), and stiffness, if the spindle overhang (A) is 100
and the spindle made from spheroidal graphite cast iron with
outside and inside diameter of 82 and 60 mm with steady load
bending moment. The cutting force at the overhung end is 180 kg.
Powered by a 12 kW motor, the spindle runs in a 50-500 R.P.M.
range. Use a roller bearing near the overhung end, and a ball
bearing...

John’s utility function is represented by the following: U(C,L)
= (C-400)*(L-100), where C is expenditure on consumption goods and
L is hours of leisure time. Suppose that John receives $150 per
week in investment income regardless of how much he works. He earns
a wage of $20 per hour. Assume that John has 110 non-sleeping hours
a week that could be devoted to work.
a.Graph John’s budget constraint.
b.Find John’s optimal amount of consumption and leisure.
c.John inherits $300,000 from...

Suppose a Cobb-Douglas Production function is given by the
following:
P(L,K)=10L0.9K0.1
where L is units of labor, K is units of capital, and
P(L,K)P(L,K) is total units that can be produced with this
labor/capital combination. Suppose each unit of labor costs $400
and each unit of capital costs $1,200. Further suppose a total of
$600,000 is available to be invested in labor and capital
(combined).
A) How many units of labor and capital should be "purchased" to
maximize production subject...

Suppose that you have estimated the following output function
where L is labor and K is capital: Y = K1/4L1/2
You know that the current price of labor is $10 and capital cost
is $150 per machine (capital).
You currently use 81 units of capital.
For #3a, the Output (Y) is 100

record EVERYTHING that one infant or toddler does in the span of
15 minutes, especially focusing on physical, cognitive and
psychosocial skills. Includes all physical activity,
all evidence of thinking, problem-solving, and language, and all
interactions with other children and adults. Record what the child
is doing, how the child appears (facial expressions, movements, how
the child carries him/herself), etc.
DO NOT SUMMARIZE anything you see. The point of a running record
is to maintain a running play-by-play account of...
