Two forces, one of which double the other has resultant of 280N. if the direction of the large force is reversed and the remaini

ng unaltered, the resultant reduces to 160N. determine the magnitude of the force and the angle between the forces.
A body weighing 210N is resting on a horizontal table.A pull of 70 applied at an angle of 21 with the horizontal just causes the body to slide over the table. calculate the normal reaction and the coefficient of friction.​

Answer:

point is 16 N.If their resultant is normal to the smaller force and has a magnitude of 8 N. Then two forces are.

Naily [24]

Answer:

(b) Anti-lock brakes

Explanation:

The short form of Anti-lock Braking System commonly known as ABS. Its working is based on the fact that the user will be in safe condition when he apply sudden brakes. It usually happens when a in vehicle moving with high speeds on highways encounter anything before them, they hit brakes suddenly which may lead to the tires loosing traction and contact with the roads and rolling over due to inertia as a result of the high speeds. These conditions result in very serious mishaps. Anti-lock system  aims to reduce the mishaps and losses which arise solely due to the locking of tires when brakes are applied. Anti-lock system significantly reduces speed and maintains a safer environment for the user and the vehicle.

How would you design a wheelchair for wheelchair-using basketball players? Would you make it more or less massive?
emmainna [20.7K]
Less, if it’s too big: hard to control and maneuverability for shooting wouldn’t be that good. a smaller wheelchair allows for faster movement and control, along with easier shooting and upper body movement

A cylindrical metal specimen having an original diameter of 12.8 mm and gauge length of 50.80 mm is pulled in tension until frac
Sedaia [141]

Answer:

%Reduction in area = 73.41%

%Reduction in elongation = 42.20%

Explanation:

Given

Original diameter = 12.8 mm

Gauge length = 50.80mm

Diameter at the point of fracture = 6.60 mm (0.260 in.)

Fractured gauge length = 72.14 mm.

%Reduction in Area is given as:

((do/2)² - (d1/2)²)/(do/2)²

Calculating percent reduction in area

do = 12.8mm, d1 = 6.6mm

So,

%RA = ((12.8/2)² - 6.6/2)²)/(12.8/2)²

%RA = 0.734130859375

%RA = 73.41%

Calculating percent reduction in elongation

%Reduction in elongation is given as:

((do) - (d1))/(d1)

do = 72.14mm, d1 = 50.80mm

So,

%RA = ((72.24) - (50.80))/(50.80)

%RA = 0.422047244094488

%RA = 42.20%
