Answer:
A combination square is a multi-use measuring instrument which is primarily used for ensuring the integrity of a 90° angle, measuring a 45° angle, measuring the center of a circular object, find depth, and simple distance measurements. It can also be used to determine level and plumb using its spirit level vial.
Explanation:
Answer:
Tech A is correct.
Explanation:
An electric brake controller is a device that sends a signal to the trailer via vehicle's brakes. This reduces the wear and tear on the vehicle brakes. As a result, the vehicle stops.
Tech A says that bleeding an electronic brake control system is just like bleeding a non-electronic brake control system.
So,
Tech A is correct.
Answer:
the width of the turning roadway = 15 ft
Explanation:
Given that:
A ramp from an expressway with a design speed(u) = 30 mi/h connects with a local road
Using 0.08 for superelevation(e)
The minimum radius of the curve on the road can be determined by using the expression:

where;
R= radius
= coefficient of friction
From the tables of coefficient of friction for a design speed at 30 mi/h ;
= 0.20
So;



R = 214.29 ft
R ≅ 215 ft
However; given that :
The turning roadway has stabilized shoulders on both sides and will provide for a onelane, one-way operation with no provision for passing a stalled vehicle.
From the tables of "Design widths of pavement for turning roads"
For a One-way operation with no provision for passing a stalled vehicle; this criteria falls under Case 1 operation
Similarly; we are told that the design vehicle is a single-unit truck; so therefore , it falls under traffic condition B.
As such in Case 1 operation that falls under traffic condition B in accordance with the Design widths of pavement for turning roads;
If the radius = 215 ft; the value for the width of the turning roadway for this conditions = 15ft
Hence; the width of the turning roadway = 15 ft
Answer:
0.1788 ,180°,90°,60°
Explanation:
CONVERSION FROM DEGREE TO RADIANS: For converting degree to radian we have to multiply with 
using this concept 10.25°=10.25×
=0.1788
CONVERSION FROM RADIAN TO DEGREE: For converting radian to degree we have to multiply with
using this concept π=π×
=180°
= ![\frac{\pi}{2}[/tex×[tex]\frac{180}{\pi}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%7D%7B2%7D%5B%2Ftex%C3%97%5Btex%5D%5Cfrac%7B180%7D%7B%5Cpi%7D)
=90°
=

=60°
Answer:
The correct answer is "
".
Explanation:
Given:
Maximum load,
P = 50,000 N
Crack length,
a = 3mm
or,
= 3×10⁻³ m
Diameter,
d = 32 mm
As we know,
⇒ Maximum stress, 


Now,
⇒ Fracture tougness, 
On substituting the values, we get
