Determine the force P required to start the movement of the wedge as shown in the Figure. Angle of friction of all contact surfaces is 15º. The inclination angle may be assumed as 40 º.I want the answer with steps plz!!!
Answers
Answer:
RN2=29.39KN
RN3=17.33KN
RN1=24.89KN
P=24.2KN
Explanation:
By using equation mode in calculator we have to find the value of RN2and RN3 then it should be substituted in equation 1 then we get RN1 the RN1 RN2 are substituted in equation 2 and the we will get the P .
Answer:
The inclination angle may be assumed as 40 º, P = 86.9 N
Explanation:
From the above question,
They have given :
The force P required to start the motion of the wedge is given by
P = μmg cos 40°
where μ is the coefficient of friction and m is the mass of the wedge.
The force P required to start the motion of the wedge is given by the equation P = μmg cos θ,
Where μ is the coefficient of friction, m is the mass of the wedge and θ is the inclination angle.
In this case, the angle of friction is 15° and the inclination angle is 40°. Thus, the force required is given by,
P = 0.3 x m x 9.8 x cos 40°
= 86.9 N.
Thus, P = 0.3 x m x 9.8 x cos 40°
P = 11.3 m x 9.8 x 0.7660
P = 86.9 N
